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 con-
     tain 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;

SEE ALSO
     scan_ip4(3), fmt_ip6(3), inet_ntop(3)
