procedure of object;CDecl; i.e. using a C ABI for a class function. If the compiler does digest this, the meaning supposedly is that the procedure gets an additional, supposedly first, parameter (hidden in Object Pascal, open in C, that is the self pointer of the instance. If the C programmer knows how to deal with the Pascal object model which of course he can, as FPC is open source, he in fact can make use of this. A variable of this type in fact consists of two pointers (code and self). This is part of the FPC Object model and ABI, so again, the C programmer can use this kind of variables if he wants to. The representation in C for such a variable would be a struct of the two pointers. But of course all this is only relevant if the C code (e.g. a shared object) is done with the FPC object model in mind, but not usable to handle foreign objects (done in C) with FPC code. -Michael _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
