Portability is more between specific compilers than between languages. If the C compiler can be configured to match whatever recordlayout the Pascal compiler is using, then it works. P.s. I'd recommend against using complex types as a parameter result. It is unoptimal. Unless there is a very good reason to pair them into a record, I'd simply use multiple var parameters, and use the return value for the success or failure indicator of the function. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
