scan_ip4(3) Library Functions Manual scan_ip4(3) NAME scan_ip4 - parse an IPv4 number in dotted-decimal notation SYNTAX #include <libowfat/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 oc- tal (like 0177.0.0.1) or hexadecimal numbers (like 0x7f000001). EXAMPLE #include <libowfat/str.h> #include <libowfat/ip4.h> char buf[]="160.45.40.10"; char ip[4]; if (scan_ip4(buf,ip) != str_len(buf)) parse_error(); SEE ALSO fmt_ip4(3), scan_ip6(3), inet_pton(3) scan_ip4(3)
