30 All declarations are optional; reasonable defaults will be used for
31 anything that isn't specified.
33 "name" is the internal name of the module. It is only used in Win16
34 modules. The default is to use the base name of the spec file (without
35 any extension). This is used for KERNEL, since it lives in
36 KRNL386.EXE. It shouldn't be needed otherwise.
38 "file" gives the name of the file containing the dll. If not specified
39 it is determined from the name of the source spec file. Normally you
40 shouldn't ever need to specify it explicitly.
42 "mode" specifies whether it is the spec file for a dll or the main exe.
43 This is only valid for Win32 spec files.
45 "heap" is the size of the module local heap (only valid for Win16
46 modules); default is no local heap.
48 "init" specifies a function which will be called when this dll
49 is loaded. This is only valid for Win32 modules.
51 "rsrc" specifies the path of the compiled resource file.
53 "ignore" specifies a list of symbols that should be ignored when
54 resolving undefined symbols against the imported libraries.
56 "ORDINAL" specified the ordinal number corresponding to the entry
57 point, or "@" for automatic ordinal allocation (Win32 only).
59 "FLAGS" is a series of optional flags, preceded by a '-' character.
60 The supported flags are:
61 "-noimport": the entry point is not made available for importing
62 from winelib applications (Win32 only).
63 "-norelay": the entry point is not displayed in relay debugging
65 "-ret64": the function returns a 64-bit value (Win32 only).
66 "-i386": the entry point is only available on i386 platforms.
67 "-register": the function uses CPU register to pass arguments.
68 "-interrupt": the function is an interrupt handler routine.
70 Lines whose first character is a '#' will be ignored as comments.
76 This type defines data storage as 32-bit words at the ordinal specified.
77 "EXPORTNAME" will be the name available for dynamic linking. "DATA"
78 can be a decimal number or a hex number preceeded by "0x". The
79 following example defines the variable "VariableA" at ordinal 2 and
82 2 variable VariableA(-1 0xff 0 0)
87 This type defines a function entry point. The prototype defined by
88 "EXPORTNAME ([ARGTYPE [ARGTYPE [...]]])" specifies the name available for
89 dynamic linking and the format of the arguments. "@" can be used
90 instead of "EXPORTNAME" for ordinal-only exports.
92 "FUNCTYPE" should be one of:
93 - "pascal16" for a Win16 function returning a 16-bit value
94 - "pascal" for a Win16 function returning a 32-bit value
95 - "stdcall" for a normal Win32 function
96 - "cdecl" for a Win32 function using the C calling convention
97 - "varargs" for a Win32 function taking a variable number of arguments
99 "ARGTYPE" should be one of:
100 - "word" (16-bit unsigned value)
101 - "s_word" (16-bit signed word)
102 - "long" (32-bit value)
103 - "double" (64-bit value)
104 - "ptr" (linear pointer)
105 - "str" (linear pointer to a null-terminated ASCII string)
106 - "wstr" (linear pointer to a null-terminated Unicode string)
107 - "segptr" (segmented pointer)
108 - "segstr" (segmented pointer to a null-terminated ASCII string)
110 Only "ptr", "str", "wstr", "long" and "double" are valid for Win32 functions.
112 "HANDLERNAME" is the name of the actual Wine function that will
113 process the request in 32-bit mode.
115 This first example defines an entry point for the CreateWindow()
116 call (the ordinal 100 is just an example):
118 100 pascal CreateWindow(ptr ptr long s_word s_word s_word s_word
122 This second example defines an entry point for the GetFocus()
123 call (the ordinal 100 is just an example):
125 100 pascal GetFocus() WIN_GetFocus()
127 To declare a function using a variable number of arguments in Win16,
128 specify the function as taking no arguments. The arguments are then
129 available with CURRENT_STACK16->args. In Win32, specify the function
130 as 'varargs' and declare it with a '...' parameter in the C file. See
131 the wsprintf* functions in user.spec and user32.spec for an example.
136 This type defines a stub function. It makes the name and ordinal
137 available for dynamic linking, but will terminate execution with an
138 error message if the function is ever called.
143 This type defines an ordinal as an absolute value.
144 "EXPORTNAME" will be the name available for dynamic linking.
145 "DATA" can be a decimal number or a hex number preceeded by "0x".
150 This type defines an entry that simply maps to a Wine symbol
151 (variable or function); "EXPORTNAME" will point to the symbol
152 "SYMBOLNAME" that must be defined in C code. This type only works with
158 This type defines an entry that is forwarded to another entry
159 point (kind of a symbolic link). "EXPORTNAME" will forward to the
160 entry point "SYMBOLNAME" that must be of the form "DLL.Function". This
161 type only works with Win32.
