htonl(9r)
NAME
  htonl, htons - General: Convert word and longword values from host-to-
  network byte order

SYNOPSIS
  #include <sys/param.h>

  unsigned int htonl(
	  unsigned int longword );

  unsigned short htons(
	  unsigned short word );

ARGUMENTS
  longword
      Specifies a 32-bit value to be conditionally byte swapped.

  word
      Specifies a 16-bit value to be conditionally byte swapped.

DESCRIPTION
  The htonl routine converts the specified longword value from host-to-
  network byte order. The htons routine converts the specified word value
  from host-to-network byte order.

  The TCP/IP protocols specify the canonical network byte order, which is big
  endian (meaning that the most significant byte is leftmost in memory).

RETURN VALUES
  Upon successful completion, the htonl routine returns the converted
  longword value in network byte order. Similarly, upon successful
  completion, the htons routine converts the specified word value in network
  byte order.
