ntohl()

PROTOTYPE

#include <sockets.h>

uint32_t ntohl(uint32_t netlong);

DESCRIPTION

ntohl() is a macro that converts 32-bit integers from network order, which is big endian, to host byte order, which may be big endian or little endian.

EXAMPLE

  /*-----------------------------------------------------------------*/
  /* Display peer's IP address and port number.                      */
  /*-----------------------------------------------------------------*/
  addrlen = sizeof(struct sockaddr_in);
  getpeername(sock, &addr, &addrlen);
  printf("Peer's IPv4 address is ");
  printIP(ntohl(addr.sin_addr));
  printf(", port is %d\n", ntohs(addr.sin_port));
