NAME

       pmemcto_malloc_usable_size - obtain size of block of memory allocated from pool

SYNOPSIS

              #include <libpmemcto.h>

              size_t pmemcto_malloc_usable_size(PMEMctopool *pcp, void *ptr);

DESCRIPTION

       The pmemcto_malloc_usable_size() function provides the same semantics as malloc_usable_size(3), but oper‐
       ates on the memory pool pcp instead of the process heap supplied by the system.  It returns the number of
       usable bytes in the block of allocated memory pointed to by ptr, a pointer to a block of memory allocated
       by pmemcto_malloc(3) or a related function.

RETURN VALUE

       The  pmemcto_malloc_usable_size()  function  returns the number of usable bytes in the block of allocated
       memory pointed to by ptr.  If ptr is NULL, 0 is returned.
