int ip4_parse (  char *  ipstr, int  network_order, int *  not_flag, unsigned *  host, unsigned *  mask )

Break an IP4 Address down into its components Parameters: ipstr  string to parse use  network order for return values (defaults to host order) not_flag  return value if the ip is negated host  ipv4 host argument mask  ipv4 mask argument Returns: 0 on sucess, else failure parsing the address Return values: -3  encountered prematurely -2  strdup failed -1  null argument -4  out of range for CIDR notation Definition at line 538 of file ipobj.c.
