NAME

6       htonl,  htons,  ntohl,  ntohs - convert values between host and network
7       byte order
8

SYNOPSIS

10       #include <net/hton.h>
11
12       unsigned long int htonl(unsigned long int hostlong);
13
14       unsigned short int htons(unsigned short int hostshort);
15
16       unsigned long int ntohl(unsigned long int netlong);
17
18       unsigned short int ntohs(unsigned short int netshort);
19

DESCRIPTION

21       The htonl() function converts the long integer hostlong from host  byte
22       order to network byte order.
23
24       The  htons()  function  converts  the short integer hostshort from host
25       byte order to network byte order.
26
27       The ntohl() function converts the long  integer  netlong  from  network
28       byte order to host byte order.
29
30       The  ntohs()  function converts the short integer netshort from network
31       byte order to host byte order.
32
33       On the z80 the host byte order is Least Significant Byte first, whereas
34       the  network  byte  order, as used on the Internet, is Most Significant
35       Byte first.

NOTES

41       Unlike on other machines  these  functions  are  not  provided  through
42       macros - they are instead functions kept in z80_crt0.lib. The optimiza‐
43       tion rules supplied with z88dk are aware of  these  routines  and  when
44       appropriate optimize the function call away.
