NAME

       scan_ip4 - parse an IPv4 number in dotted-decimal notation

SYNTAX

       #include <ip4.h>

       int scan_ip4(const char *src,char ip[4]);

DESCRIPTION

       scan_ip4  parses an IPv4 number in dotted-decimal ASCII representation from src and writes
       the result into ip. It returns the number of bytes read from  src  or  0  if  the  parsing
       failed.

       Unlike many other IP parsing routines, scan_ip4 does not recognize octal (like 0177.0.0.1)
       or hexadecimal numbers (like 0x7f000001).

EXAMPLE

       #include <str.h>
       #include <ip4.h>

         char buf[]="160.45.40.10";
         char ip[4];
         if (scan_ip4(buf,ip) != str_len(buf))
           parse_error();
