In general, you can use function attributes on function pointers like this: void * (* __attribute__ ((malloc)) my_malloc) (size_t) = malloc; Unfortunately, this is only supported for some attributes. It will only work if the attribute can be attached to a function type rather than to a specific function declaration. The malloc attribute is not implemented in that way, so this does not work for the malloc attribute. I don't think it would be very difficult to implement this if you are interested in trying. Ian
