NAME

       ost::IPV4Cidr -

       The CIDR class is used to support routing tables and validate address
       policies.

SYNOPSIS

       #include <address.h>

Member Function Documentation

   struct in_addr ost::IPV4Cidr::getBroadcast (void) const [read]
       Compute the broadcast address associated with this cidr. Returns:
           system binary coded network address.

   unsigned ost::IPV4Cidr::getMask (const char * cp) const [protected]
   struct in_addr ost::IPV4Cidr::getNetmask (void) const [inline, read]
       Get network mask associated with this cidr. Returns:
           system binary coded network mask.

   struct in_addr ost::IPV4Cidr::getNetwork (void) const [inline, read]
       Get network address associated with this cidr. Returns:
           system binary coded address.

   bool ost::IPV4Cidr::isMember (const struct in_addr & inaddr) const
       See if a low level address object is a member of this cidr’s net.
       Parameters:
           inaddr object to test.

       Returns:
           true if member of cidr.

   bool ost::IPV4Cidr::isMember (const struct sockaddr * saddr) const
       See if a socket address is a member of this cidr’s network. Parameters:
           saddr pointer to test.

       Returns:
           true if member of cidr.

   bool ost::IPV4Cidr::operator== (const struct in_addr & a) const [inline]
   bool ost::IPV4Cidr::operator== (const struct sockaddr * a) const [inline]
   void ost::IPV4Cidr::set (const char * cidr)
       Set the cidr from a full or partial hostname, or from an address/mask,
       or a host/bits specification. Parameters:
           cidr string to use.
