NNG_LISTENER_START(3) NNG Reference Manual NNG_LISTENER_START(3)

nng_listener_start - start listener

#include <nng/nng.h>
int nng_listener_start(nng_listener l, int flags);

The nng_listener_start() function starts the listener l.

This causes the listener to bind to the address it was created with, and to start accepting connections from remote dialers. Each new connection results in an nng_pipe object, which will be attached to the listener’s socket.

The flags argument is ignored, but reserved for future use.

Once a listener has started, it is generally not possible to change its configuration.

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

NNG_ECLOSED

Parameter l does not refer to an open listener.

NNG_ESTATE

The listener l is already started.
