NAME

fmt_ip4 - write a formatted ASCII representation of an IPv4 number

CONTENTS

Syntax
Description
Example

SYNTAX

#include <ip4.h>

unsigned int fmt_ip4(char *dest,const char ip[4]);

DESCRIPTION

fmt_ip4 formats an IPv4 number in dotted-decimal ASCII representation from ip and writes the result into dest. It returns the number of bytes written.

If dest equals FMT_LEN (i.e. is zero), fmt_ip4 returns the number of bytes it would have written.

fmt_ip4 does not append \0.

For convenience, ip4.h defines the integer IP4_FMT to be big enough to contain every possible fmt_ip4 output plus \0.

EXAMPLE

#include <ip4.h>

char buf[IP4_FMT];
char ip[4];
buf[fmt_ip4(buf,ip)]=0;
