SYNOPSIS

|

#include <network.h>

|
|
int inet_aton(const char *cp, struct in_addr *inp);

|
|
|
| 13 |
|
|
unsigned long int inet_addr(const char *cp);

DESCRIPTION
|
| 18 |
|
|
inet_aton() converts the Internet host address cp from the
|
| 19 |
|
|
standard numbers-and-dots notation into binary data and
|
| 20 |
|
|
stores it in the structure that inp points to. inet_aton
|
| 21 |
|
|
returns nonzero if the address is valid, zero if not.
|
| 22 |
|
|
|
| 23 |
|
|
The inet_addr() function converts the Internet host
|
| 24 |
|
|
address cp from numbers-and-dots notation into binary data
|
| 25 |
|
|
in network byte order. If the input is invalid,
|
| 26 |
|
|
INADDR_NONE (usually -1) is returned. This is an obsolete
|
| 27 |
|
|
interface to inet_aton, described immediately above; it is
|
| 28 |
|
|
obsolete because -1 is a valid address (255.255.255.255),
|
| 29 |
|
|
and inet_aton provides a cleaner way to indicate error
|
| 30 |
|
|
return.
|
| 31 |
|
|
|
| 32 |
|
|
The inet_ntoa() function converts the Internet host
|
| 33 |
|
|
address in given in network byte order to a string in
|
| 34 |
|
|
standard numbers-and-dots notation. The string is
|
| 35 |
|
|
returned in a statically allocated buffer, which subse
|
| 36 |
|
|
quent calls will overwrite.
