== NAME
|
||
|
|
|
||
|
|
nng_free - free memory
|
||
|
|
|
||
|
|
== SYNOPSIS
|
||
|
|
|
||
|
|
[source, c]
|
||
|
|
----
|
||
|
|
#include <nng/nng.h>
|
||
|
|
|
||
|
|
void nng_free(void *ptr, size_t size);
|
||
|
|
----
|
||
|
|
|
||
|
|
== DESCRIPTION
|
||
|
|
|
||
|
|
The `nng_free()` function deallocates a memory region of size _size_,
|
||
|
|
that was previously allocated by xref:nng_alloc.3.adoc[`nng_alloc()`] or
|
||
|
|
xref:nng_recv.3.adoc[`nng_recv()`] with the `NNG_FLAG_ALLOC` flag.
|
||
|
|
|
||
|
|
IMPORTANT: It is very important that _size_ match the allocation size
|
||
|
|
used to allocate the memory.
|
||
|
|
|
||
|
|
IMPORTANT: Do not attempt to use this function to deallocate memory
|
||
|
|
obtained by a call to the system `malloc()` or `calloc()` functions,
|
||
|
|
or the {cpp} `new` operator.
|
||
|
|
Doing so may result in unpredictable
|
||
|
|
behavior, including corruption of application memory.
|
||
|
|
|
||
|
