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();
