You don't. The C standard (unlike POSIX¹) does not require C implementations to support casts between function pointers and void *, though this feature is mentioned as a common extension in the non-normative Annex J.5.7. If you need a type that can hold a pointer to anything (object or function), a union could be an option. Philipp ¹ I haven't checked the POSIX stanard now, but AFAIR, while POSIX still allows such casts, it is considered an obsolescent feature there. _______________________________________________ Sdcc-user mailing list Sdcc-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sdcc-user
