fmt_ip4(3)		   Library Functions Manual		    fmt_ip4(3)

NAME
       fmt_ip4 - write a formatted ASCII representation	of an IPv4 number

SYNTAX
       #include	<libowfat/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	<libowfat/ip4.h>

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