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;
