NAME
       nn_freemsg - deallocate a message

SYNOPSIS
       #include <nanomsg/nn.h>

       int nn_freemsg (void *msg);

DESCRIPTION
       Deallocates a message allocated using nn_allocmsg(3) function or
       received via nn_recv(3) or nn_recvmsg(3) function. While nn_recv(3) and
       nn_recvmsg(3) allow to receive data into arbitrary buffers, using
       library-allocated buffers can be more efficient for large messages as
       it allows for using zero-copy techniques.

RETURN VALUE
       If the function succeeds zero is returned. Otherwise, -1 is returned
       and errno is set to to one of the values defined below.

ERRORS
       EFAULT
	   The message pointer is invalid.

EXAMPLE
	   void *buf;
	   nn_recv (s, &buf, NN_MSG, 0);
	   nn_freemsg (buf);

SEE ALSO
       nn_allocmsg(3) nn_reallocmsg(3) nn_recv(3) nn_recvmsg(3) nanomsg(7)
