5 modbus_tcp_pi_listen - create and listen a TCP PI Modbus socket (IPv6)
10 int modbus_tcp_pi_listen(modbus_t *ctx, int nb_connection);
15 The *modbus_tcp_pi_listen()* function shall create a socket and listen to
16 maximum `nb_connection` incoming connections on the specified nodes. The
17 context *ctx* must be allocated and initialized with [modbus_new_tcp_pi](modbus_new_tcp_pi)
18 before to set the node to listen, if node is set to NULL or '0.0.0.0', any addresses will be
23 The function shall return a new socket if successful. Otherwise it shall return
28 For detailed examples, see source files in tests directory:
30 - unit-test-server.c, simple but handle only one connection
35 ctx = modbus_new_tcp_pi("::0", "502");
36 s = modbus_tcp_pi_listen(ctx, 1);
37 modbus_tcp_pi_accept(ctx, &s);
40 rc = modbus_receive(ctx, query);
41 modbus_replay(ctx, query, rc, mb_mapping);
