// The #GCond struct is an opaque data structure that represents a
// condition. Threads can block on a #GCond if they find a certain
// condition to be false. If other threads change the state of this
// condition they signal the #GCond, and that causes the waiting
// threads to be woken up.
// 
// Consider the following example of a shared variable.  One or more
// threads can wait for data to be published to the variable and when
// another thread publishes the data, it can signal one of the waiting
// threads to wake up to collect the data.
// 
// <example>
// <title>
// Using GCond to block a thread until a condition is satisfied
// </title>
// <programlisting>
// gpointer current_data = NULL;
// GMutex data_mutex;
// GCond data_cond;
// 
// void
// push_data (gpointer data)
// {

// g_cond_wait (&data_cond, &data_mutex);
// data = current_data;
// current_data = NULL;
// g_mutex_unlock (&data_mutex);

// </example>
// 
// Whenever a thread calls pop_data() now, it will wait until
// current_data is non-%NULL, i.e. until some other thread
// has called push_data().
// 
// The example shows that use of a condition variable must always be
// paired with a mutex.  Without the use of a mutex, there would be a
// race between the check of <varname>current_data</varname> by the
// while loop in <function>pop_data</function> and waiting.
// Specifically, another thread could set <varname>pop_data</varname>
// after the check, and signal the cond (with nobody waiting on it)
// before the first thread goes to sleep.  #GCond is specifically useful
// for its ability to release the mutex and go to sleep atomically.
// 
// It is also important to use the g_cond_wait() and g_cond_wait_until()
// functions only inside a loop which checks for the condition to be
// true.  See g_cond_wait() for an explanation of why the condition may
// not be true even after it returns.

// The #GMutex struct is an opaque data structure to represent a mutex

// <programlisting>
// int
// give_me_next_number (void)
// {
// static int current_number = 0;
// 
// /<!-- -->* now do a very complicated calculation to calculate the new

// *<!-- -->/
// current_number = calc_next_number (current_number);

// <example>
// <title>Using GMutex to protected a shared variable</title>
// <programlisting>
// int
// give_me_next_number (void)

// static GMutex mutex;

// ret_val = current_number = calc_next_number (current_number);
// g_mutex_unlock (&amp;mutex);

// return ret_val;
// }
// </programlisting>
// </example>
// 
// Notice that the #GMutex is not initialised to any particular value.
// Its placement in static storage ensures that it will be initialised
// to all-zeros, which is appropriate.
// 
// If a #GMutex is placed in other contexts (eg: embedded in a struct)

// between read-only ('reader') and full ('writer') access. While only
// one thread at a time is allowed write access (by holding the 'writer'
// lock via g_rw_lock_writer_lock()), multiple threads can gain

// 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.

// exec(). Actions taken in this function will only affect the child,

// 
// On Windows, the function is called in the parent. Its usefulness on
// Windows is thus questionable. In many cases executing the child setup
// function in the parent can have ill effects, and you should be very
// careful when porting software to Windows that uses child setup
// functions.
// 
// However, even on POSIX, you are extremely limited in what you can
// safely do from a #GSpawnChildSetupFunc, because any mutexes that
// were held by other threads in the parent process at the time of the
// fork() will still be locked in the child process, and they will
// never be unlocked (since the threads that held them don't exist in
// the child). POSIX allows only async-signal-safe functions (see
// <citerefentry><refentrytitle>signal</refentrytitle><manvolnum>7</manvolnum></citerefentry>)
// to be called in the child between fork() and exec(), which
// drastically limits the usefulness of child setup functions.

// In particular, it is not safe to call any function which may
// call malloc(), which includes POSIX functions such as setenv().
// If you need to set up the child environment differently from

// #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.  (However, #GVariant's serialisation format is not the same
// as the serialisation format of a D-Bus message body: use #GDBusMessage,
// in the gio library, for those.)
// 
// For space-efficiency, the #GVariant serialisation format does not
// automatically include the variant's type or endianness, which must
// either be implied from context (such as knowledge that a particular
// file format always contains a little-endian %G_VARIANT_TYPE_VARIANT)
// or supplied out-of-band (for instance, a type and/or endianness
// indicator could be placed at the beginning of a file, network message
// or network stream).
// 
// A #GVariant's size is limited mainly by any lower level operating
// system constraints, such as the number of bits in #gsize.  For
// example, it is reasonable to have a 2GB file mapped into memory
// with #GMappedFile, and call g_variant_new_from_data() on it.
// 
// 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.

// <refsect3 id="gvariant-serialised-data-memory">
// <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

// 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

// Variants use the same amount of space as the item inside of the

// </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

// <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

// </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).

// precede any g_dgettext() invocations.  For GTK+, it means calling
// textdomain() before gtk_init or its variants.

// Note that this behavior may not be desired for example if an application
// has its untranslated messages in a language other than English.  In those

// 
// 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 child's environment. If @envp is %NULL, the child inherits its

// 
// @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 child watch 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 child watch is equivalent to calling waitpid() or handling
// the <literal>SIGCHLD</literal> signal manually. On Windows, calling g_spawn_close_pid()
// is equivalent to calling CloseHandle() on the process handle returned
// in @child_pid).  See g_child_watch_add().
// 
// %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

// 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
