Convert a string into an Internet network number
#include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> in_addr_t inet_network( const char * cp );
The inet_network() routine converts a string representing an IPv4 Internet address (for example, 127.0.0.1) into a numeric Internet network number.
All Internet addresses are returned in network order (bytes are ordered from left to right). All network numbers and local address parts are returned as machine-format integer values. For more information on Internet addresses, see inet_net_ntop().
An Internet network number, or INADDR_NONE if an error occurred.
