Converts longwords from network to host byte order.
#include <in.h> unsigned long int ntohl (unsigned long int netlong);
The network byte order is the format in which data bytes are supposed to be transmitted through a network. All hosts on a network must send data in network byte order. Not all hosts have an internal data representation format that is identical to the network byte order. The host byte order is the format in which bytes are ordered internally on a specific host.
The host byte order on VAX systems differs from the network order.
This routine is most often used with Internet addresses and ports as returned by gethostent and getservent, and when manipulating values in the structures. Network byte order places the byte with the most significant bits at lower addresses; VAX systems place the most significant bits at the highest address.
