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