73 * Rational of XBT_PUBLIC:
74 * * If you build the DLL you must pass the right value of XBT_PUBLIC in the project : to do this you must define the DLL_EXPORT macro
75 * * If you do a static compilation, you must define the macro DLL_STATIC
76 * * If you link your code against the DLL, this file defines the macro to '__declspec(dllimport)' for you
77 * * If you compile under unix, this file defines the macro to 'extern', even if it's not mandatory with modern compilers
79 * Rational of XBT_PUBLIC_NO_IMPORT:
80 * * This is for symbols which must be exported in the DLL, but not imported from it.
81 * This is obviously useful for initialized globals (which cannot be extern or similar).
82 * This is also used in the log mecanism where a macro creates the variable automatically.
83 * When the macro is called from within SimGrid, the symbol must be exported, but when called
84 * from within the client code, it must not try to retrieve the symbol from the DLL since it's not in there.
