SYNOPSIS
#include
<malloc/malloc.h>
size_t
malloc_good_size
(size_t
size);
size_t
malloc_size
(const void
*ptr);
DESCRIPTION
The
malloc_size
()
function returns the size of the memory block that backs the allocation
pointed to by ptr. The memory block size is always at
least as large as the allocation it backs, and may be larger.
The
malloc_good_size
()
function rounds size up to a value that the allocator
implementation can allocate without adding any padding; it then returns that
rounded-up value.
