NAME
nng_alloc - allocate memory
SYNOPSIS
DESCRIPTION
The nng_alloc() function allocates a contiguous memory region of
at least size bytes.
The memory will be 64-bit aligned.
The returned memory can be used to hold message buffers, in which
case it can be directly passed to nng_send() using
the flag NNG_FLAG_ALLOC. Alternatively, it can be freed when no
longer needed using nng_free().
Do not use the system free() function to release this memory.
On some platforms this may work, but it is not guaranteed and may lead
to a crash or other undesirable and unpredictable behavior.

RETURN VALUES
This function returns a pointer to the allocated memory on success,
and NULL otherwise.
ERRORS
No errors are returned, but a NULL return value should be
treated the same as NNG_ENOMEM.
