It's an opaque structure. You know it's a record, but you don't know what is inside it =) An encapsulation techinique common in the c world. In the end always a pointer to the structure will be used (wither by really using a pointer or a var parameter), and it is not created or released on your side of the program, so you don't need to know it's contents or size or anything else. -- Felipe Monteiro de Carvalho _______________________________________________ fpc-devel maillist - [email protected] http://lists.freepascal.org/mailman/listinfo/fpc-devel
