May it would be a solution if the C-compiler which compiles the library generates a 'generic library interface file' or something similar with all necessary information. Because the compiler has all the information. From this 'generic library interface file' it will be easier to convert a pascal header interface file. Or the C-compiler generates it directly for pascal. ---> 'pascal library interface file' or similar... That I can imagine could be a solution, but the C-compiler programmers have to implement this function. The full meaning-context can be read in the original C-header file then. > _______________________________________________ > fpc-pascal maillist - fpc-pascal@lists.freepascal.org > http://lists.freepascal.org/mailman/listinfo/fpc-pascal _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
