This kind of parameters do not exist on tradiional mac compilers, you have to use pointers. > test data is probably allocated > test data handle pointer is allocated. > > but the pointer in between is missing. > > +----------------+ +-----------------+ +----------+ > | test data handle | ->| test data pointer | -> | test data | > +----------------+ +-----------------+ +----------+ > > ( By changing the declarion like i mentioned the problem could be solved > ;) ) > > Though it depends on what this routine does: > > testDataHandle(NewHandleClear(sizeof(testData))); > > It seems to be just clearing the data... No, this is a Mac OS routine to allocate a zeroed block of memory, which is pointed to by a mac "handle", which is simply a pointer to a pointer. This kind of handles will be automatically reallocated if needed, to keep memory unfragmented. > Maybe you should post some more code... how the structure and pointers are > allocated. > > And maybe a description of the routine and it's prototype ;) > > So to me it seems the structures etc are a bit f*cked up ;) They are OK :) > If that's not the case... and you are 100% sure you know what you doing yhen > it's probably something totally else... and I should just butt out... lol. Yes, I think so :) Olle _______________________________________________ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal
