The API do seem wrong here, casting an int to a pointer isn't generally safe. It should probably be changed to take a socket pointer instead, e.g.: gnutls_transport_set_ptr(session->sess, (gnutls_transport_ptr_t) &fd); But this break all existing uses. We could invent a new API and deprecate this one. Opinions? Suggestions for the API name? If there is some easier solution, i.e, if POSIX or something says that void* must be able to hold all int values, and there is some workaround to avoid the warning, maybe we can recommend that instead. Updating all callers to this function is rather tedious work, especially if all it solves is to get rid of a warning.
