90 * Basically, any symbols defined in the include/directory must be
91 * like this (plus some other globals).
93 * UNIX coders should just think of it as a special way to say "extern".
95 * * If you build the DLL, define the DLL_EXPORT symbol so that all symbols
96 * actually get exported by this file.
98 * * If you do a static windows compilation, define DLL_STATIC, both when
99 * compiling the application files and when compiling the library.
101 * * If you link your application against the DLL or if you do a UNIX build,
102 * don't do anything special. This file will do the right thing for you
106 * Rational of XBT_EXPORT_NO_IMPORT: (windows-only cruft)
107 * * Symbols which must be exported in the DLL, but not imported from it.
109 * * This is obviously useful for initialized globals (which cannot be
110 * extern or similar).
111 * * This is also used in the log mecanism where a macro creates the
112 * variable automatically. When the macro is called from within SimGrid,
113 * the symbol must be exported, but when called from within the client
114 * code, it must not try to retrieve the symbol from the DLL since it's
117 * Rational of XBT_IMPORT_NO_EXPORT: (windows-only cruft)
118 * * Symbols which must be imported from the DLL, but not explicitely
121 * * The root log category is already exported, but not imported explicitely
122 * when creating a subcategory since we cannot import the parent category
123 * to deal with the fact that the parent may be in application space, not
