Use the -l c option to qcc to link against this library. This library is usually included automatically.
The ntohl() function converts a 32-bit value from network-byte order to host-byte order. If a machine's byte order is the same as the network order, this routine is defined as a null macro.
You most often use this routine in conjunction with internet addresses and ports returned by gethostbyname() and getservent().
The value in host-byte order.
