| /* Function calling conventions. | |
| * ============================= | |
| * Normally it is not necessary to specify to the compiler how to call | |
| * a function - it just does it - however on x86 systems derived from | |
| * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems | |
| * and some others) there are multiple ways to call a function and the | |
| * default can be changed on the compiler command line. For this reason | |
| * libpng specifies the calling convention of every exported function and | |
| * every function called via a user supplied function pointer. This is | |
| * done in this file by defining the following macros: | |
| * | |
| * PNGAPI Calling convention for exported functions. | |
| * PNGCBAPI Calling convention for user provided (callback) functions. | |
| * PNGCAPI Calling convention used by the ANSI-C library (required | |
| * for longjmp callbacks and sometimes used internally to | |
| * specify the calling convention for zlib). | |
| * | |
| * These macros should never be overridden. If it is necessary to | |
| * change calling convention in a private build this can be done | |
| * by setting PNG_API_RULE (which defaults to 0) to one of the values | |
| * below to select the correct 'API' variants. | |
| * | |
| * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout. | |
| * This is correct in every known environment. | |
| * PNG_API_RULE=1 Use the operating system convention for PNGAPI and | |
| * the 'C' calling convention (from PNGCAPI) for | |
| * callbacks (PNGCBAPI). This is no longer required | |
| * in any known environment - if it has to be used | |
| * please post an explanation of the problem to the | |
| * libpng mailing list. | |
| * | |
| * These cases only differ if the operating system does not use the C | |
| * calling convention, at present this just means the above cases | |
| * (x86 DOS/Windows sytems) and, even then, this does not apply to | |
| * Cygwin running on those systems. | |
| * | |
| * Note that the value must be defined in pnglibconf.h so that what | |
| * the application uses to call the library matches the conventions | |
| * set when building the library. | |
| */ | |
| /* Symbol export | |
| * ============= | |
| * When building a shared library it is almost always necessary to tell | |
| * the compiler which symbols to export. The png.h macro 'PNG_EXPORT' | |
| * is used to mark the symbols. On some systems these symbols can be | |
| * extracted at link time and need no special processing by the compiler, | |
| * on other systems the symbols are flagged by the compiler and just | |
| * the declaration requires a special tag applied (unfortunately) in a | |
| * compiler dependent way. Some systems can do either. | |
| * | |
| * A small number of older systems also require a symbol from a DLL to | |
| * be flagged to the program that calls it. This is a problem because | |
| * we do not know in the header file included by application code that | |
| * the symbol will come from a shared library, as opposed to a statically | |
| * linked one. For this reason the application must tell us by setting | |
| * the magic flag PNG_USE_DLL to turn on the special processing before | |
| * it includes png.h. | |
| * | |
| * Four additional macros are used to make this happen: | |
| * | |
| * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from | |
| * the build or imported if PNG_USE_DLL is set - compiler | |
| * and system specific. | |
| * | |
| * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to | |
| * 'type', compiler specific. | |
| * | |
| * PNG_DLL_EXPORT Set to the magic to use during a libpng build to | |
| * make a symbol exported from the DLL. Not used in the | |
| * public header files; see pngpriv.h for how it is used | |
| * in the libpng build. | |
| * | |
| * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come | |
| * from a DLL - used to define PNG_IMPEXP when | |
| * PNG_USE_DLL is set. | |
| */ | |
| /* System specific discovery. | |
| * ========================== | |
| * This code is used at build time to find PNG_IMPEXP, the API settings | |
| * and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL | |
| * import processing is possible. On Windows systems it also sets | |
| * compiler-specific macros to the values required to change the calling | |
| * conventions of the various functions. | |
