SYNOPSIS

#include <sys/types.h>
#include <netinet/in.h>

unsigned short htons(unsigned short hostshort);

DESCRIPTION

The htons macro converts an unsigned short integer hostshort from host byte order to network byte order. On an IBM 370, this is a null macro since IBM 370 byte ordering is big endian, as is network byte ordering.

RETURN VALUE

htons returns the converted value.

CAUTION

There is also an htons function. Be sure to include the proper header files so that the htons macro is always used.

PORTABILITY

htons is portable to other environments, including most UNIX systems, that implement BSD sockets.

IMPLEMENTATION

The htons macro is defined in the <netinet/in.h> header file.
