NN_TERM(3) nanomsg 1.1.5 NN_TERM(3) NAME nn_term - notify all sockets about process termination SYNOPSIS #include <nanomsg/nn.h> void nn_term (void); DESCRIPTION To help with shutdown of multi-threaded programs nanomsg provides the nn_term() function which closes all open sockets, and releases all related resources. If a socket is blocked inside a blocking function, such as nn_recv(3), it will be unblocked and EBADF error will be returned to the user. Subsequent calls on such sockets will also return EBADF. Attempting to open a new socket with nn_socket(3) will result in an ETERM error. If waiting for NN_SNDFD or NN_RCVFD using a polling function, such as poll() or select(), the call will unblock with both NN_SNDFD and NN_RCVFD signaled. EXAMPLE s = nn_socket (AF_SP, NN_PAIR); nn_term (); rc = nn_send (s, "ABC", 3, 0); assert (rc == -1 && errno == EBADF); SEE ALSO nn_close(3) nn_send(3) nn_socket(3) nn_recv(3) nanomsg(7) AUTHORS Martin Sustrik <sustrik@250bpm.com> Garrett D'Amore <garrett@damore.org> 2018-10-15 NN_TERM(3)
