// The #GMutex struct is an opaque data structure to represent a mutex
// (mutual exclusion). It can be used to protect data against shared
// access. Take for example the following function:
// 
// <example>
// <title>A function which will not work in a threaded environment</title>
// <programlisting>
// int
// give_me_next_number (void)
// {
// static int current_number = 0;
// 
// /<!-- -->* now do a very complicated calculation to calculate the new
// * number, this might for example be a random number generator
// *<!-- -->/
// current_number = calc_next_number (current_number);
// 
// return current_number;
// }
// </programlisting>
// </example>
// 
// It is easy to see that this won't work in a multi-threaded
// application. There current_number must be protected against shared
// access. A first naive implementation would be:
// 
// <example>
// <title>The wrong way to write a thread-safe function</title>
// <programlisting>
// int
// give_me_next_number (void)
// {
// static int current_number = 0;
// int ret_val;
// static GMutex * mutex = NULL;
// 
// if (!mutex) mutex = g_mutex_new (<!-- -->);
// 
// g_mutex_lock (mutex);
// ret_val = current_number = calc_next_number (current_number);
// g_mutex_unlock (mutex);
// 
// return ret_val;
// }
// </programlisting>
// </example>
// 
// This looks like it would work, but there is a race condition while
// constructing the mutex and this code cannot work reliable. Please do
// not use such constructs in your own programs! One working solution
// is:
// 
// <example>
// <title>A correct thread-safe function</title>
// <programlisting>
// static GMutex *give_me_next_number_mutex = NULL;
// 
// /<!-- -->* this function must be called before any call to
// * give_me_next_number(<!-- -->)
// *
// * it must be called exactly once.
// *<!-- -->/
// void
// init_give_me_next_number (void)
// {
// g_assert (give_me_next_number_mutex == NULL);
// give_me_next_number_mutex = g_mutex_new (<!-- -->);
// }
// 
// int
// give_me_next_number (void)
// {
// static int current_number = 0;
// int ret_val;
// 
// g_mutex_lock (give_me_next_number_mutex);
// ret_val = current_number = calc_next_number (current_number);
// g_mutex_unlock (give_me_next_number_mutex);
// 
// return ret_val;
// }
// </programlisting>
// </example>
// 
// #GStaticMutex provides a simpler and safer way of doing this.
// 
// If you want to use a mutex, and your code should also work without
// calling g_thread_init() first, then you cannot use a #GMutex, as
// g_mutex_new() requires that the thread system be initialized. Use a
// #GStaticMutex instead.
// 
// A #GMutex should only be accessed via the following functions.
//

// The <function>g_regex_*()</function> functions implement regular
// expression pattern matching using syntax and semantics similar to
// Perl regular expression.
// 
// Some functions accept a @start_position argument, setting it differs
// from just passing over a shortened string and setting #G_REGEX_MATCH_NOTBOL
// in the case of a pattern that begins with any kind of lookbehind assertion.
// For example, consider the pattern "\Biss\B" which finds occurrences of "iss"
// in the middle of words. ("\B" matches only if the current position in the
// subject is not a word boundary.) When applied to the string "Mississipi"
// from the fourth byte, namely "issipi", it does not match, because "\B" is
// always false at the start of the subject, which is deemed to be a word
// boundary. However, if the entire string is passed , but with
// @start_position set to 4, it finds the second occurrence of "iss" because
// it is able to look behind the starting point to discover that it is
// preceded by a letter.
// 
// Note that, unless you set the #G_REGEX_RAW flag, all the strings passed
// to these functions must be encoded in UTF-8. The lengths and the positions
// inside the strings are in bytes and not in characters, so, for instance,
// "\xc3\xa0" (i.e. "&agrave;") is two bytes long but it is treated as a
// single character. If you set #G_REGEX_RAW the strings can be non-valid
// UTF-8 strings and a byte is treated as a character, so "\xc3\xa0" is two
// bytes and two characters long.
// 
// When matching a pattern, "\n" matches only against a "\n" character in
// the string, and "\r" matches only a "\r" character. To match any newline
// sequence use "\R". This particular group matches either the two-character
// sequence CR + LF ("\r\n"), or one of the single characters LF (linefeed,
// U+000A, "\n"), VT vertical tab, U+000B, "\v"), FF (formfeed, U+000C, "\f"),
// CR (carriage return, U+000D, "\r"), NEL (next line, U+0085), LS (line
// separator, U+2028), or PS (paragraph separator, U+2029).
// 
// The behaviour of the dot, circumflex, and dollar metacharacters are
// affected by newline characters, the default is to recognize any newline
// character (the same characters recognized by "\R"). This can be changed
// with #G_REGEX_NEWLINE_CR, #G_REGEX_NEWLINE_LF and #G_REGEX_NEWLINE_CRLF
// compile options, and with #G_REGEX_MATCH_NEWLINE_ANY,
// #G_REGEX_MATCH_NEWLINE_CR, #G_REGEX_MATCH_NEWLINE_LF and
// #G_REGEX_MATCH_NEWLINE_CRLF match options. These settings are also
// relevant when compiling a pattern if #G_REGEX_EXTENDED is set, and an
// unescaped "#" outside a character class is encountered. This indicates
// a comment that lasts until after the next newline.
// 
// Creating and manipulating the same #GRegex structure from different
// threads is not a problem as #GRegex does not modify its internal
// state between creation and destruction, on the other hand #GMatchInfo
// is not threadsafe.

// The #GStaticRWLock struct represents a read-write lock. A read-write
// lock can be used for protecting data that some portions of code only
// read from, while others also write. In such situations it is
// desirable that several readers can read at once, whereas of course
// only one writer may write at a time. Take a look at the following
// example:
// 
// <example>
// <title>An array with access functions</title>
// <programlisting>
// GStaticRWLock rwlock = G_STATIC_RW_LOCK_INIT;
// GPtrArray *array;
// 
// gpointer
// my_array_get (guint index)
// {
// gpointer retval = NULL;
// 
// if (!array)
// return NULL;
// 
// g_static_rw_lock_reader_lock (&amp;rwlock);
// if (index &lt; array->len)
// retval = g_ptr_array_index (array, index);
// g_static_rw_lock_reader_unlock (&amp;rwlock);
// 
// return retval;
// }
// 
// void
// my_array_set (guint index, gpointer data)
// {
// g_static_rw_lock_writer_lock (&amp;rwlock);
// 
// if (!array)
// array = g_ptr_array_new (<!-- -->);
// 
// if (index >= array->len)
// g_ptr_array_set_size (array, index+1);
// g_ptr_array_index (array, index) = data;
// 
// g_static_rw_lock_writer_unlock (&amp;rwlock);
// }
// </programlisting>
// </example>
// 
// This example shows an array which can be accessed by many readers
// (the <function>my_array_get()</function> function) simultaneously,
// whereas the writers (the <function>my_array_set()</function>
// function) will only be allowed once at a time and only if no readers
// currently access the array. This is because of the potentially
// dangerous resizing of the array. Using these functions is fully
// multi-thread safe now.
// 
// Most of the time, writers should have precedence over readers. That
// means, for this implementation, that as soon as a writer wants to
// lock the data, no other reader is allowed to lock the data, whereas,
// of course, the readers that already have locked the data are allowed
// to finish their operation. As soon as the last reader unlocks the
// data, the writer will lock it.
// 
// Even though #GStaticRWLock is not opaque, it should only be used
// with the following functions.
// 
// All of the <function>g_static_rw_lock_*</function> functions can be
// used even if g_thread_init() has not been called. Then they do
// nothing, apart from <function>g_static_rw_lock_*_trylock</function>,
// which does nothing but returning %TRUE.
// 
// <note><para>A read-write lock has a higher overhead than a mutex. For
// example, both g_static_rw_lock_reader_lock() and
// g_static_rw_lock_reader_unlock() have to lock and unlock a
// #GStaticMutex, so it takes at least twice the time to lock and unlock
// a #GStaticRWLock that it does to lock and unlock a #GStaticMutex. So
// only data structures that are accessed by multiple readers, and which
// keep the lock for a considerable time justify a #GStaticRWLock. The
// above example most probably would fare better with a

// #GVariant is a variant datatype; it stores a value along with
// information about the type of that value.  The range of possible
// values is determined by the type.  The type system used by #GVariant
// is #GVariantType.
// 
// #GVariant instances always have a type and a value (which are given
// at construction time).  The type and value of a #GVariant instance
// can never change other than by the #GVariant itself being
// destroyed.  A #GVariant cannot contain a pointer.
// 
// #GVariant is reference counted using g_variant_ref() and
// g_variant_unref().  #GVariant also has floating reference counts --
// see g_variant_ref_sink().
// 
// #GVariant is completely threadsafe.  A #GVariant instance can be
// concurrently accessed in any way from any number of threads without
// problems.
// 
// #GVariant is heavily optimised for dealing with data in serialised
// form.  It works particularly well with data located in memory-mapped
// files.  It can perform nearly all deserialisation operations in a
// small constant time, usually touching only a single memory page.
// Serialised #GVariant data can also be sent over the network.
// 
// #GVariant is largely compatible with D-Bus.  Almost all types of
// #GVariant instances can be sent over D-Bus.  See #GVariantType for
// exceptions.
// 
// For convenience to C programmers, #GVariant features powerful
// varargs-based value construction and destruction.  This feature is
// designed to be embedded in other libraries.
// 
// There is a Python-inspired text language for describing #GVariant
// values.  #GVariant includes a printer for this language and a parser
// with type inferencing.
// 
// <refsect2>
// <title>Memory Use</title>
// <para>
// #GVariant tries to be quite efficient with respect to memory use.
// This section gives a rough idea of how much memory is used by the
// current implementation.  The information here is subject to change
// in the future.
// </para>
// <para>
// The memory allocated by #GVariant can be grouped into 4 broad
// purposes: memory for serialised data, memory for the type
// information cache, buffer management memory and memory for the
// #GVariant structure itself.
// </para>
// <refsect3>
// <title>Serialised Data Memory</title>
// <para>
// This is the memory that is used for storing GVariant data in
// serialised form.  This is what would be sent over the network or
// what would end up on disk.
// </para>
// <para>
// The amount of memory required to store a boolean is 1 byte.  16,
// 32 and 64 bit integers and double precision floating point numbers
// use their "natural" size.  Strings (including object path and
// signature strings) are stored with a nul terminator, and as such
// use the length of the string plus 1 byte.
// </para>
// <para>
// Maybe types use no space at all to represent the null value and
// use the same amount of space (sometimes plus one byte) as the
// equivalent non-maybe-typed value to represent the non-null case.
// </para>
// <para>
// Arrays use the amount of space required to store each of their
// members, concatenated.  Additionally, if the items stored in an
// array are not of a fixed-size (ie: strings, other arrays, etc)
// then an additional framing offset is stored for each item.  The
// size of this offset is either 1, 2 or 4 bytes depending on the
// overall size of the container.  Additionally, extra padding bytes
// are added as required for alignment of child values.
// </para>
// <para>
// Tuples (including dictionary entries) use the amount of space
// required to store each of their members, concatenated, plus one
// framing offset (as per arrays) for each non-fixed-sized item in
// the tuple, except for the last one.  Additionally, extra padding
// bytes are added as required for alignment of child values.
// </para>
// <para>
// Variants use the same amount of space as the item inside of the
// variant, plus 1 byte, plus the length of the type string for the
// item inside the variant.
// </para>
// <para>
// As an example, consider a dictionary mapping strings to variants.
// In the case that the dictionary is empty, 0 bytes are required for
// the serialisation.
// </para>
// <para>
// If we add an item "width" that maps to the int32 value of 500 then
// we will use 4 byte to store the int32 (so 6 for the variant
// containing it) and 6 bytes for the string.  The variant must be
// aligned to 8 after the 6 bytes of the string, so that's 2 extra
// bytes.  6 (string) + 2 (padding) + 6 (variant) is 14 bytes used
// for the dictionary entry.  An additional 1 byte is added to the
// array as a framing offset making a total of 15 bytes.
// </para>
// <para>
// If we add another entry, "title" that maps to a nullable string
// that happens to have a value of null, then we use 0 bytes for the
// null value (and 3 bytes for the variant to contain it along with
// its type string) plus 6 bytes for the string.  Again, we need 2
// padding bytes.  That makes a total of 6 + 2 + 3 = 11 bytes.
// </para>
// <para>
// We now require extra padding between the two items in the array.
// After the 14 bytes of the first item, that's 2 bytes required.  We
// now require 2 framing offsets for an extra two bytes.  14 + 2 + 11
// + 2 = 29 bytes to encode the entire two-item dictionary.
// </para>
// </refsect3>
// <refsect3>
// <title>Type Information Cache</title>
// <para>
// For each GVariant type that currently exists in the program a type
// information structure is kept in the type information cache.  The
// type information structure is required for rapid deserialisation.
// </para>
// <para>
// Continuing with the above example, if a #GVariant exists with the
// type "a{sv}" then a type information struct will exist for
// "a{sv}", "{sv}", "s", and "v".  Multiple uses of the same type
// will share the same type information.  Additionally, all
// single-digit types are stored in read-only static memory and do
// not contribute to the writable memory footprint of a program using
// #GVariant.
// </para>
// <para>
// Aside from the type information structures stored in read-only
// memory, there are two forms of type information.  One is used for
// container types where there is a single element type: arrays and
// maybe types.  The other is used for container types where there
// are multiple element types: tuples and dictionary entries.
// </para>
// <para>
// Array type info structures are 6 * sizeof (void *), plus the
// memory required to store the type string itself.  This means that
// on 32bit systems, the cache entry for "a{sv}" would require 30
// bytes of memory (plus malloc overhead).
// </para>
// <para>
// Tuple type info structures are 6 * sizeof (void *), plus 4 *
// sizeof (void *) for each item in the tuple, plus the memory
// required to store the type string itself.  A 2-item tuple, for
// example, would have a type information structure that consumed
// writable memory in the size of 14 * sizeof (void *) (plus type
// string)  This means that on 32bit systems, the cache entry for
// "{sv}" would require 61 bytes of memory (plus malloc overhead).
// </para>
// <para>
// This means that in total, for our "a{sv}" example, 91 bytes of
// type information would be allocated.
// </para>
// <para>
// The type information cache, additionally, uses a #GHashTable to
// store and lookup the cached items and stores a pointer to this
// hash table in static storage.  The hash table is freed when there
// are zero items in the type cache.
// </para>
// <para>
// Although these sizes may seem large it is important to remember
// that a program will probably only have a very small number of
// different types of values in it and that only one type information
// structure is required for many different values of the same type.
// </para>
// </refsect3>
// <refsect3>
// <title>Buffer Management Memory</title>
// <para>
// #GVariant uses an internal buffer management structure to deal
// with the various different possible sources of serialised data
// that it uses.  The buffer is responsible for ensuring that the
// correct call is made when the data is no longer in use by
// #GVariant.  This may involve a g_free() or a g_slice_free() or
// even g_mapped_file_unref().
// </para>
// <para>
// One buffer management structure is used for each chunk of
// serialised data.  The size of the buffer management structure is 4
// * (void *).  On 32bit systems, that's 16 bytes.
// </para>
// </refsect3>
// <refsect3>
// <title>GVariant structure</title>
// <para>
// The size of a #GVariant structure is 6 * (void *).  On 32 bit
// systems, that's 24 bytes.
// </para>
// <para>
// #GVariant structures only exist if they are explicitly created
// with API calls.  For example, if a #GVariant is constructed out of
// serialised data for the example given above (with the dictionary)
// then although there are 9 individual values that comprise the
// entire dictionary (two keys, two values, two variants containing
// the values, two dictionary entries, plus the dictionary itself),
// only 1 #GVariant instance exists -- the one referring to the
// dictionary.
// </para>
// <para>
// If calls are made to start accessing the other values then
// #GVariant instances will exist for those values only for as long
// as they are in use (ie: until you call g_variant_unref()).  The
// type information is shared.  The serialised data and the buffer
// management structure for that serialised data is shared by the
// child.
// </para>
// </refsect3>
// <refsect3>
// <title>Summary</title>
// <para>
// To put the entire example together, for our dictionary mapping
// strings to variants (with two entries, as given above), we are
// using 91 bytes of memory for type information, 29 byes of memory
// for the serialised data, 16 bytes for buffer management and 24
// bytes for the #GVariant instance, or a total of 160 bytes, plus
// malloc overhead.  If we were to use g_variant_get_child_value() to
// access the two dictionary entries, we would use an additional 48
// bytes.  If we were to have other dictionaries of the same type, we
// would use more memory for the serialised data and buffer
// management for those dictionaries, but the type information would
// be shared.

// This section introduces the GVariant type system.  It is based, in
// large part, on the D-Bus type system, with two major changes and some minor
// lifting of restrictions.  The <ulink
// url='http://dbus.freedesktop.org/doc/dbus-specification.html'>DBus
// specification</ulink>, therefore, provides a significant amount of
// information that is useful when working with GVariant.
// 
// The first major change with respect to the D-Bus type system is the
// introduction of maybe (or "nullable") types.  Any type in GVariant can be
// converted to a maybe type, in which case, "nothing" (or "null") becomes a
// valid value.  Maybe types have been added by introducing the
// character "<literal>m</literal>" to type strings.
// 
// The second major change is that the GVariant type system supports the
// concept of "indefinite types" -- types that are less specific than
// the normal types found in D-Bus.  For example, it is possible to speak
// of "an array of any type" in GVariant, where the D-Bus type system
// would require you to speak of "an array of integers" or "an array of
// strings".  Indefinite types have been added by introducing the
// characters "<literal>*</literal>", "<literal>?</literal>" and
// "<literal>r</literal>" to type strings.
// 
// Finally, all arbitrary restrictions relating to the complexity of
// types are lifted along with the restriction that dictionary entries
// may only appear nested inside of arrays.
// 
// Just as in D-Bus, GVariant types are described with strings ("type
// strings").  Subject to the differences mentioned above, these strings
// are of the same form as those found in DBus.  Note, however: D-Bus
// always works in terms of messages and therefore individual type
// strings appear nowhere in its interface.  Instead, "signatures"
// are a concatenation of the strings of the type of each argument in a
// message.  GVariant deals with single values directly so GVariant type
// strings always describe the type of exactly one value.  This means
// that a D-Bus signature string is generally not a valid GVariant type
// string -- except in the case that it is the signature of a message
// containing exactly one argument.
// 
// An indefinite type is similar in spirit to what may be called an
// abstract type in other type systems.  No value can exist that has an
// indefinite type as its type, but values can exist that have types
// that are subtypes of indefinite types.  That is to say,
// g_variant_get_type() will never return an indefinite type, but
// calling g_variant_is_of_type() with an indefinite type may return
// %TRUE.  For example, you cannot have a value that represents "an
// array of no particular type", but you can have an "array of integers"
// which certainly matches the type of "an array of no particular type",
// since "array of integers" is a subtype of "array of no particular
// type".
// 
// This is similar to how instances of abstract classes may not
// directly exist in other type systems, but instances of their
// non-abstract subtypes may.  For example, in GTK, no object that has
// the type of #GtkBin can exist (since #GtkBin is an abstract class),
// but a #GtkWindow can certainly be instantiated, and you would say
// that the #GtkWindow is a #GtkBin (since #GtkWindow is a subclass of
// #GtkBin).

// Specifies a function to be called at normal program termination.
// 
// Since GLib 2.8.2, on Windows g_atexit() actually is a preprocessor
// macro that maps to a call to the atexit() function in the C
// library. This means that in case the code that calls g_atexit(),
// i.e. atexit(), is in a DLL, the function will be called when the
// DLL is detached from the program. This typically makes more sense
// than that the function is called when the GLib DLL is detached,
// which happened earlier when g_atexit() was a function in the GLib
// DLL.
// 
// The behaviour of atexit() in the context of dynamically loaded
// modules is not formally specified and varies wildly.
// 
// On POSIX systems, calling g_atexit() (or atexit()) in a dynamically
// loaded module which is unloaded before the program terminates might
// well cause a crash at program exit.
// 
// Some POSIX systems implement atexit() like Windows, and have each
// dynamically loaded module maintain an own atexit chain that is
// called when the module is unloaded.
// 
// On other POSIX systems, before a dynamically loaded module is
// unloaded, the registered atexit functions (if any) residing in that
// module are called, regardless where the code that registered them
// resided. This is presumably the most robust approach.
// 
// As can be seen from the above, for portability it's best to avoid
// calling g_atexit() (or atexit()) except in the main executable of a
// program.

// should be a %NULL-terminated array of strings, to be passed as the
// argument vector for the child. The first string in @argv is of
// course the name of the program to execute. By default, the name of
// the program must be a full path; the <envar>PATH</envar> shell variable
// will only be searched if you pass the %G_SPAWN_SEARCH_PATH flag.
// 
// On Windows, note that all the string or string vector arguments to
// this function and the other g_spawn*() functions are in UTF-8, the
// GLib file name encoding. Unicode characters that are not part of
// the system codepage passed in these arguments will be correctly
// available in the spawned program only if it uses wide character API
// to retrieve its command line. For C programs built with Microsoft's
// tools it is enough to make the program have a wmain() instead of
// main(). wmain() has a wide character argument vector as parameter.
// 
// At least currently, mingw doesn't support wmain(), so if you use
// mingw to develop the spawned program, it will have to call the
// undocumented function __wgetmainargs() to get the wide character
// argument vector and environment. See gspawn-win32-helper.c in the
// GLib sources or init.c in the mingw runtime sources for a prototype
// for that function. Alternatively, you can retrieve the Win32 system
// level wide character command line passed to the spawned program
// using the GetCommandLineW() function.
// 
// On Windows the low-level child process creation API
// <function>CreateProcess()</function> doesn't use argument vectors,
// but a command line. The C runtime library's
// <function>spawn*()</function> family of functions (which
// g_spawn_async_with_pipes() eventually calls) paste the argument
// vector elements together into a command line, and the C runtime startup code
// does a corresponding reconstruction of an argument vector from the
// command line, to be passed to main(). Complications arise when you have
// argument vector elements that contain spaces of double quotes. The
// <function>spawn*()</function> functions don't do any quoting or
// escaping, but on the other hand the startup code does do unquoting
// and unescaping in order to enable receiving arguments with embedded
// spaces or double quotes. To work around this asymmetry,
// g_spawn_async_with_pipes() will do quoting and escaping on argument
// vector elements that need it before calling the C runtime
// spawn() function.
// 
// The returned @child_pid on Windows is a handle to the child
// process, not its identifier. Process handles and process
// identifiers are different concepts on Windows.
// 
// @envp is a %NULL-terminated array of strings, where each string
// has the form <literal>KEY=VALUE</literal>. This will become
// the child's environment. If @envp is %NULL, the child inherits its
// parent's environment.
// 
// @flags should be the bitwise OR of any flags you want to affect the
// function's behaviour. The %G_SPAWN_DO_NOT_REAP_CHILD means that
// the child will not automatically be reaped; you must use a
// #GChildWatch source to be notified about the death of the child
// process. Eventually you must call g_spawn_close_pid() on the
// @child_pid, in order to free resources which may be associated
// with the child process. (On Unix, using a #GChildWatch source is
// equivalent to calling waitpid() or handling the %SIGCHLD signal
// manually. On Windows, calling g_spawn_close_pid() is equivalent
// to calling CloseHandle() on the process handle returned in
// @child_pid).
// 
// %G_SPAWN_LEAVE_DESCRIPTORS_OPEN means that the parent's open file
// descriptors will be inherited by the child; otherwise all
// descriptors except stdin/stdout/stderr will be closed before
// calling exec() in the child. %G_SPAWN_SEARCH_PATH
// means that <literal>argv[0]</literal> need not be an absolute path, it
// will be looked for in the user's <envar>PATH</envar>.
// %G_SPAWN_STDOUT_TO_DEV_NULL means that the child's standard output will
// be discarded, instead of going to the same location as the parent's
// standard output. If you use this flag, @standard_output must be %NULL.
// %G_SPAWN_STDERR_TO_DEV_NULL means that the child's standard error
// will be discarded, instead of going to the same location as the parent's
// standard error. If you use this flag, @standard_error must be %NULL.
// %G_SPAWN_CHILD_INHERITS_STDIN means that the child will inherit the parent's
// standard input (by default, the child's standard input is attached to
// /dev/null). If you use this flag, @standard_input must be %NULL.
// %G_SPAWN_FILE_AND_ARGV_ZERO means that the first element of @argv is
// the file to execute, while the remaining elements are the
// actual argument vector to pass to the file. Normally
// g_spawn_async_with_pipes() uses @argv[0] as the file to execute, and
// passes all of @argv to the child.
// 
// @child_setup and @user_data are a function and user data. On POSIX
// platforms, the function is called in the child after GLib has
// performed all the setup it plans to perform (including creating
// pipes, closing file descriptors, etc.) but before calling
// exec(). That is, @child_setup is called just
// before calling exec() in the child. Obviously
// actions taken in this function will only affect the child, not the
// parent.
// 
// On Windows, there is no separate fork() and exec()
// functionality. Child processes are created and run with a single
// API call, CreateProcess(). There is no sensible thing @child_setup
// could be used for on Windows so it is ignored and not called.
// 
// If non-%NULL, @child_pid will on Unix be filled with the child's
// process ID. You can use the process ID to send signals to the
// child, or to use g_child_watch_add() (or waitpid()) if you specified the
// %G_SPAWN_DO_NOT_REAP_CHILD flag. On Windows, @child_pid will be
// filled with a handle to the child process only if you specified the
// %G_SPAWN_DO_NOT_REAP_CHILD flag. You can then access the child
// process using the Win32 API, for example wait for its termination
// with the <function>WaitFor*()</function> functions, or examine its
// exit code with GetExitCodeProcess(). You should close the handle
// with CloseHandle() or g_spawn_close_pid() when you no longer need it.
// 
// If non-%NULL, the @standard_input, @standard_output, @standard_error
// locations will be filled with file descriptors for writing to the child's
// standard input or reading from its standard output or standard error.
// The caller of g_spawn_async_with_pipes() must close these file descriptors
// when they are no longer in use. If these parameters are %NULL, the corresponding
// pipe won't be created.
// 
// If @standard_input is NULL, the child's standard input is attached to
// /dev/null unless %G_SPAWN_CHILD_INHERITS_STDIN is set.
// 
// If @standard_error is NULL, the child's standard error goes to the same
// location as the parent's standard error unless %G_SPAWN_STDERR_TO_DEV_NULL
// is set.
// 
// If @standard_output is NULL, the child's standard output goes to the same
// location as the parent's standard output unless %G_SPAWN_STDOUT_TO_DEV_NULL
// is set.
// 
// @error can be %NULL to ignore errors, or non-%NULL to report errors.
// If an error is set, the function returns %FALSE. Errors
// are reported even if they occur in the child (for example if the
// executable in <literal>argv[0]</literal> is not found). Typically
// the <literal>message</literal> field of returned errors should be displayed
// to users. Possible errors are those from the #G_SPAWN_ERROR domain.
// 
// If an error occurs, @child_pid, @standard_input, @standard_output,
// and @standard_error will not be filled with valid values.
// 
// If @child_pid is not %NULL and an error does not occur then the returned
