The assignment is not uneccesary: On success, realloc returns a pointer to the new area and the old pointer becomes invalid. If the allocation can be extended in place, realloc may just return the old pointer, however, if it can't, it will return a pointer to some newly-allocated storage and the old will be freed. _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
