freeSized

Frees the memory pointed to by mem, assuming it is has the given size.

If mem is null this is a no-op (and size is ignored).

It is an error if size doesn’t match the size passed when mem was allocated. size is passed to this function to allow optimizations in the allocator. If you don’t know the allocation size, use [glib.global.gfree] instead.

In case a GCC compatible compiler is used, this function may be used automatically via [glib.global.gfree] if the allocated size is known at compile time, since GLib 2.78.
