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 .

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

EXAMPLE
       #include <ip4.h>

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