NNG_LISTENER_CLOSE(3) NNG Reference Manual NNG_LISTENER_CLOSE(3)

nng_listener_close - close listener

#include <nng/nng.h>
int nng_listener_close(nng_listener l);

The nng_listener_close() function closes the listener l. This also closes any pipes that have been created by the listener.

Once this function returns, the listener l and any of its resources are deallocated. Therefore it is an error to attempt to access l after this function has returned. (Attempts to do so will result in NNG_ECLOSED errors.)

Listeners are implicitly closed when the socket they are associated with is closed.

This function returns 0 on success, and non-zero otherwise.

NNG_ECLOSED

Parameter l does not refer to an open listener.
