Provided by: libnng-dev_1.9.0-2_amd64 bug

NAME

       nng_listener_id - return numeric listener identifier

SYNOPSIS

           #include <nng/nng.h>

           int nng_listener_id(nng_listener l);

DESCRIPTION

       The nng_listener_id() function returns a positive identifier for the listener l, if it is
       valid. Otherwise it returns -1.

           Note
           A listener is considered valid if it was ever created with the nng_listener_create()
           or nng_listen() functions. listeners that are allocated on the stack or statically
           should be initialized with the macro NNG_LISTENER_INITIALIZER to ensure that they
           cannot be confused with a valid listener before they are created properly.

RETURN VALUES

       This function returns the positive value for the listener identifier, or -1 if the
       listener is invalid.

ERRORS

       None.
