98 | /* Function calling conventions. | ||
99 | * ============================= | ||
100 | * Normally it is not necessary to specify to the compiler how to call | ||
101 | * a function - it just does it - however on x86 systems derived from | ||
102 | * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems | ||
103 | * and some others) there are multiple ways to call a function and the | ||
104 | * default can be changed on the compiler command line. For this reason | ||
105 | * libpng specifies the calling convention of every exported function and | ||
106 | * every function called via a user supplied function pointer. This is | ||
107 | * done in this file by defining the following macros: | ||
108 | * | ||
109 | * PNGAPI Calling convention for exported functions. | ||
110 | * PNGCBAPI Calling convention for user provided (callback) functions. | ||
111 | * PNGCAPI Calling convention used by the ANSI-C library (required | ||
112 | * for longjmp callbacks and sometimes used internally to | ||
113 | * specify the calling convention for zlib). | ||
114 | * | ||
115 | * These macros should never be overridden. If it is necessary to | ||
116 | * change calling convention in a private build this can be done | ||
117 | * by setting PNG_API_RULE (which defaults to 0) to one of the values | ||
118 | * below to select the correct 'API' variants. | ||
119 | * | ||
120 | * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout. | ||
121 | * This is correct in every known environment. | ||
122 | * PNG_API_RULE=1 Use the operating system convention for PNGAPI and | ||
123 | * the 'C' calling convention (from PNGCAPI) for | ||
124 | * callbacks (PNGCBAPI). This is no longer required | ||
125 | * in any known environment - if it has to be used | ||
126 | * please post an explanation of the problem to the | ||
127 | * libpng mailing list. | ||
128 | * | ||
129 | * These cases only differ if the operating system does not use the C | ||
130 | * calling convention, at present this just means the above cases | ||
131 | * (x86 DOS/Windows sytems) and, even then, this does not apply to | ||
132 | * Cygwin running on those systems. | ||
133 | * | ||
134 | * Note that the value must be defined in pnglibconf.h so that what | ||
135 | * the application uses to call the library matches the conventions | ||
136 | * set when building the library. | ||
137 | */ | ||
138 | |||
139 | /* Symbol export | ||
140 | * ============= | ||
141 | * When building a shared library it is almost always necessary to tell | ||
142 | * the compiler which symbols to export. The png.h macro 'PNG_EXPORT' | ||
143 | * is used to mark the symbols. On some systems these symbols can be | ||
144 | * extracted at link time and need no special processing by the compiler, | ||
145 | * on other systems the symbols are flagged by the compiler and just | ||
146 | * the declaration requires a special tag applied (unfortunately) in a | ||
147 | * compiler dependent way. Some systems can do either. | ||
148 | * | ||
149 | * A small number of older systems also require a symbol from a DLL to | ||
150 | * be flagged to the program that calls it. This is a problem because | ||
151 | * we do not know in the header file included by application code that | ||
152 | * the symbol will come from a shared library, as opposed to a statically | ||
153 | * linked one. For this reason the application must tell us by setting | ||
154 | * the magic flag PNG_USE_DLL to turn on the special processing before | ||
155 | * it includes png.h. | ||
156 | * | ||
157 | * Four additional macros are used to make this happen: | ||
158 | * | ||
159 | * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from | ||
160 | * the build or imported if PNG_USE_DLL is set - compiler | ||
161 | * and system specific. | ||
162 | * | ||
163 | * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to | ||
164 | * 'type', compiler specific. | ||
165 | * | ||
166 | * PNG_DLL_EXPORT Set to the magic to use during a libpng build to | ||
167 | * make a symbol exported from the DLL. Not used in the | ||
168 | * public header files; see pngpriv.h for how it is used | ||
169 | * in the libpng build. | ||
170 | * | ||
171 | * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come | ||
172 | * from a DLL - used to define PNG_IMPEXP when | ||
173 | * PNG_USE_DLL is set. | ||
174 | */ | ||
175 | |||

180 | * import processing is possible. On Windows/x86 systems it also sets | ||
