inet_network example in c

/* inet_network.c: * example illustrates how the inet_network(3) function can be used. * The program also calls upon the htonl function to display how the * value looks in network endian order * Example using inet_network(3): */ #include <stdio.h> #include <unistd.h> #include <stdlib.h> #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> int main(int argc,char **argv) { int x; const char *addr[] = { "44.135.86.12", "127.0.0.1", "172.16.23.95", "192.168.9.1" }; unsigned long net_addr; for ( x=0; x<4; ++x ) { net_addr = inet_network(addr[x]); printf("%14s = 0x%05X net 0x%05X\n", addr[x],net_addr, (unsigned long)htonl(net_addr)); } return 0; } /* * OUTPUT * [sgupta@rhel54x64 socket]$ gcc inet_network.c -o inet_network [sgupta@rhel54x64 socket]$ ./inet_network 44.135.86.12 = 0x2C87560C net 0xC56872C 127.0.0.1 = 0x7F000001 net 0x100007F 172.16.23.95 = 0xAC10175F net 0x5F1710AC 192.168.9.1 = 0xC0A80901 net 0x109A8C0 [sgupta@rhel54x64 socket]$ */
