Returns the size of a memory block
#include <library.h>
size_t library_msize (
void *addr);
(IN) Points to a memory block previously allocated by a call to library_calloc, library_malloc, or library_realloc.
Returns the size of the memory block pointed to by addr.
This function is indistinguishable from the msize function and is only provided to complete the logical set of memory management functions in library.h.
