SYNOPSIS

#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 nng_alloc() or nng_recv() with the NNG_FLAG_ALLOC flag.

It is very important that size match the allocation size used to allocate the memory.
Do not attempt to use this function to deallocate memory obtained by a call to the system malloc() or calloc() functions, or the C++ new operator. Doing so may result in unpredictable behavior, including corruption of application memory.

RETURN VALUES

None.

ERRORS

None.
