nng_alloc(3)
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
.
