If i write a program like this, how could i free up the memory that i have malloc ? unsigned short get_mem(unsigned short *string, size_t len) { string = (unsigned short *)malloc(sizeof(unsigned short)*len); return string; } main() { unsigned short *text; text = get_mem(text, 10); /* then if i try to use free(text); here or in another function, then it will get me a errormessge... */ /* messges like "DAMAGE: after a Normal block..." */ return 0; } What should i do? or do i need to free() anything at all? Thanks very much for any help

If you''re using C, it''s considered bad style to cast void pointers.

Um, how are you supposed to allocate memory in C if you don''t cast void pointers? That''s what malloc returns.

I think WW was referring to the fact that an explicit cast is unnecessary, because C allows conversion from a void* to any other pointer type. (Yet another reason that C++ is NOT a superset of C).

How appropriate. You fight like a cow.
