       The libmodbus documentation was written by Stéphane Raimbault <stephane.raimbault@gmail.com>

libmodbus v3.1.6                                   12/09/2019                            MODBUS_TCP_PI_ACCEPT(3)

       The modbus_tcp_pi_accept() function shall extract the first connection on the queue of pending
       connections, create a new socket and store it in libmodbus context given in argument. If available,
       accept4() with SOCK_CLOEXEC will be called instead of accept().

       For detailed example, see unit-test-server.c source file in tests directory.

           ...

           ctx = modbus_new_tcp_pi("::0", 502);
           s = modbus_tcp_pi_listen(ctx, 1);
           modbus_tcp_pi_accept(ctx, &s);

           ...

           close(s)
           modbus_free(ctx);
