NAME

       fmt_ip4 - write a formatted ASCII representation of an IPv4 number

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;
