/* Handle import/export stuff
- * Rational:
+ *
+ * Rational of XBT_PUBLIC:
* * 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
* * If you do a static compilation, you must define the macro DLL_STATIC
* * If you link your code against the DLL, this file defines the macro to '__declspec(dllimport)' for you
* * If you compile under unix, this file defines the macro to 'extern', even if it's not mandatory with modern compilers
+ *
+ * Rational of XBT_PUBLIC_NO_IMPORT:
+ * * This is for 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 mecanism 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.
