InetMaskAddress3cc
Internet addresses used specifically as masking addresses (such as ' 255.255.255.0') are held in the inetmaskaddress derived object. internet address mask such as subnet masks.
Usage
#include <socket.h>
Inherits InetAddress.
Public Methods
InetMaskAddress (const char *mask)
Create the mask from a null terminated ASCII string such as '255.255.255.128'. InetAddress & operator= (unsigned long addr)
Allows assignment from the return of functions like inet_addr() or htonl().
Friends
InetHostAddress operator & (const InetHostAddress &addr, const InetMaskAddress &mask)
Masks are usually used to coerce host addresses into a specific router or class domain.
Detailed description
Internet addresses used specifically as masking addresses (such as ' 255.255.255.0') are held in the InetMaskAddress derived object. Internet Address Mask such as subnet masks.
The seperate class is used so that C++ type casting can automatically determine when an InetAddress object is really a mask address object rather than simply using the base class. This also allows manipulative operators for address masking to operate only when presented with a Masked address as well as providing cleaner and safer source.
