htonl(9r)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
Specifies a 32-bit value to be conditionally byte swapped. 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 mem‐
ory).
RETURN VALUES
Upon successful completion, the htonl routine returns the converted
longword value in network byte order. Similarly, upon successful com‐
pletion, the htons routine converts the specified word value in network
byte order.
