/* Handle import/export stuff
*
* Rational of XBT_PUBLIC:
* * This is for library symbols visible from the application-land.
* Basically, any symbols defined in the include/directory must be like this (plus some other globals).
*
* UNIX coders should just think of it as a special way to say "extern".
*
* * If you build the DLL, define the DLL_EXPORT symbol so that all symbols actually get exported by this file.
*
* * If you link your application against the DLL or if you do a UNIX build, don't do anything special. This file
* will do the right thing for you by default.
*
* Rational of XBT_EXPORT_NO_IMPORT: (windows-only)
* * Symbols which must be exported in the DLL, but not imported from it.
*
* * This is obviously useful for initialized globals (which cannot be extern or similar).
* * This is also used in the log mechanism where a macro creates the variable automatically. When the macro is
* called from within SimGrid, the symbol must be exported, but when called from within the client code, it must
* not try to retrieve the symbol from the DLL since it's not in there.
*
* Rational of XBT_IMPORT_NO_EXPORT: (windows-only)
* * Symbols which must be imported from the DLL, but not explicitly exported from it.
*
* * The root log category is already exported, but not imported explicitly when creating a subcategory since we
* cannot import the parent category to deal with the fact that the parent may be in application space, not DLL
* space.
