SYNOPSIS

          void *
          bson_aligned_alloc0 (size_t alignment, size_t num_bytes);

PARAMETERS

       • alignment:  The  alignment  of  the  allocated  bytes of memory. Must be a power of 2 and a multiple of
         sizeof (void *).

       • num_bytes: The number of bytes to allocate. Must be a multiple of alignment.

DESCRIPTION

       This is a portable aligned_alloc() wrapper that also sets the memory to zero.

       If there was a failure to allocate num_bytes bytes aligned to alignment, the process will be aborted.

       Warning:
          This function will abort on failure to allocate memory.

RETURNS

       A pointer to a memory region which HAS been zeroed.
