SYNOPSIS

10       int modbus_tcp_pi_accept(modbus_t *ctx, int *'s);
11

DESCRIPTION

13       The modbus_tcp_pi_accept() function shall extract the first connection
14       on the queue of pending connections, create a new socket and store it
15       in libmodbus context given in argument. If available, accept4() with
16       SOCK_CLOEXEC will be called instead of accept().
17

RETURN VALUE

19       The function shall return a new socket if successful. Otherwise it
20       shall return -1 and set errno.
