NAME

       pmemcto_aligned_alloc - allocate aligned memory

SYNOPSIS

              #include <libpmemcto.h>

              void *pmemcto_aligned_alloc(PMEMctopool *pcp, size_t alignment, size_t size);

DESCRIPTION

       The  pmemcto_aligned_alloc() function provides the same semantics as aligned_alloc(3), but
       operates on the memory pool pcp instead of the process heap supplied by  the  system.   It
       allocates  size  bytes from the memory pool and returns a pointer to the allocated memory.
       The memory is not zeroed.  The memory address will be a multiple of alignment, which  must
       be a power of two.

RETURN VALUE

       On  success,  pmemcto_aligned_alloc()  function returns a pointer to the allocated memory.
       If size is 0, then pmemcto_aligned_alloc() returns either NULL, or a unique pointer  value
       that  can  later be successfully passed to pmemcto_free(3).  If pmemcto_aligned_alloc() is
       unable to satisfy the allocation request, a NULL pointer is  returned  and  errno  is  set
       appropriately.

ERRORS

       EINVAL alignment was not a power of two.

       ENOMEM Insufficient memory available to satisfy allocation request.
