nng_listener_start3
Start listener
Usage
#include <nng/nng.h> int nng_listener_start(nng_listener l, int flags);
Overview
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.
Return values
This function returns 0 on success, and non-zero otherwise.
Errors
NNG_ECLOSED
Parameter l does not refer to an open listener.
NNG_ESTATE
The listener l is already started.
