SYNOPSIS

10       cc [ flag ... ] file ... -lxnet [ library ... ]
11       #include <arpa/inet.h>

DESCRIPTION

26       These functions convert 16-bit and 32-bit  quantities  between  network
27       byte order and host byte order.
28
29
30       The   uint32_t  and   uint16_t types are made available by inclusion of
31       <inttypes.h>.

USAGE

34       These functions are  most  often  used  in  conjunction  with  Internet
35       addresses  and  ports  as  returned  by  gethostent(3XNET)  and getser‐
36       vent(3XNET).
37
38
39       On some architectures these functions are defined as macros that expand
40       to the value of their argument.
41

RETURN VALUES

43       The  htonl()  and htons() functions return the argument value converted
44       from host to network byte order.
45
46
47       The ntohl() and ntohs() functions return the argument  value  converted
48       from network to host byte order.
