37 /* Package version identification: formerly specified as a simple
38 * dotted numeric pair representing major.minor, this doesn't adapt
39 * well to the inclusion of the patch-level, since the dotted triplet
40 * representation of major.minor.patch is not a valid representation
41 * of a numeric entity. Thus, from version 3.18 onwards we adopt a
42 * representation which encodes the version as a long integer value,
45 * __W32API_VERSION = 1,000,000 * major + 1,000 * minor + patch
47 * DO NOT EDIT these package version assignments manually; they are
48 * derived from the package version specification within configure.ac,
49 * whence they are propagated automatically, at package build time.

56 /* The underlying operating system platform version, and its
57 * identifying macros for application support, are established by:
59 #include <sdkddkver.h>
61 /* The following defines are for documentation purposes. Although not used
62 * within it, they were provided in earlier versions of the Win32 API, as a
63 * convenience for users who wished to symbolically declare a minimum level
64 * of required operating system and Internet Explorer version support, when
65 * assigning WINVER, _WIN32_WINDOWS, _WIN32_WINNT, and _WIN32_IE values.
67 * Each of the following "old name" macros is now considered deprecated in
68 * favour of manifest "preferred name" macro definitions from <sdkddkver.h>.
69 * Hence, redefine each in terms of the appropriate "preferred name" macro;
70 * new code should avoid the old names, and use the preferred name instead.
73 * _WIN32_WINDOWS and/or WINVER may be set to any of the following manifest
74 * values, to specify a minimum Win9x support level requirement:
76 * Old Name Preferred Name
77 * ------------- ------------------
79 #define Windows95 _WIN32_WINDOWS_95
80 #define Windows98 _WIN32_WINDOWS_98

83 /* _WIN32_WINNT and/or WINVER may be set to any of the following manifest
84 * values, to specify a minimum WinNT support level requirement:
86 * Old Name Preferred Name

118 /* Only Microsoft could attempt to justify this insanity: when building
119 * a UTF-16LE application -- apparently their understanding of Unicode is
120 * limited to this -- the C/C++ runtime requires that the user must define
121 * the _UNICODE macro, while to use the Windows API's UTF-16LE capabilities,
122 * it is the UNICODE macro, (without the leading underscore), which must be
123 * defined. The (bogus) explanation appears to be that it is the C standard
124 * which dictates the requirement for the leading underscore, to avoid any
125 * possible conflict with a user defined symbol; (bogus because the macro
126 * must be user defined anyway -- it is not a private symbol -- and in
127 * any case, the Windows API already reserves the UNICODE symbol as
128 * a user defined macro, with equivalent intent.
130 * The real explanation, of course, is that this is just another example
131 * of Microsoft irrationality; in any event, there seems to be no sane
132 * scenario in which defining one without the other would be required,
133 * or indeed would not raise potential for internal inconsistency, so we
134 * ensure that either both are, or neither is defined.

141 /* Related to the UNICODE macro definition, there are many functions in
142 * the Win32 API with a generic name, which is mapped to a variant with
143 * wchar_t UTF-16LE encoding of string arguments, in cases when UNICODE
144 * is defined, as facilitated by the following macro...
147 /* ...by appending a "W" suffix to the generic function name...
149 # define __AW_SUFFIXED__(__NAME__) __NAME__##W

152 * char encoding of string arguments, when UNICODE is not defined.
154 # define __AW_SUFFIXED__(__NAME__) __NAME__##A
156 /* Further related, the __AW_EXTENDED__ macro reproduces the effect of
157 * __AW_SUFFIXED__, with the addition of a single underscore character
158 * separating the base name from the appropriate suffix.

165 * this requires a two stage expansion, to ensure that the "L" prefix

167 * than just to the defining macro name).
