ost::IPV4Mask(3) Library Functions Manual ost::IPV4Mask(3) NAME
ost::IPV4Mask - Internet addresses used specifically as masking addresses (such as ' 255.255.255.0') are held in the IPV4Mask derived object. SYNOPSIS
#include <address.h> Inherits ost::IPV4Address. Public Member Functions IPV4Mask (const char *mask) Create the mask from a null terminated ASCII string such as '255.255.255.128'. IPV4Address & operator= (unsigned long addr) Allows assignment from the return of functions like inet_addr() or htonl() Friends __EXPORT IPV4Host operator& (const IPV4Host &addr, const IPV4Mask &mask) Masks are usually used to coerce host addresses into a specific router or class domain. Additional Inherited Members Detailed Description Internet addresses used specifically as masking addresses (such as ' 255.255.255.0') are held in the IPV4Mask derived object. The separate class is used so that C++ type casting can automatically determine when an IPV4Address 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.

Constructor &; Destructor Documentation ost::IPV4Mask::IPV4Mask (const char *mask) Create the mask from a null terminated ASCII string such as '255.255.255.128'. Parameters: mask null terminated ASCII mask string. Member Function Documentation IPV4Address& ost::IPV4Mask::operator= (unsigned longaddr) [inline] Allows assignment from the return of functions like inet_addr() or htonl() Reimplemented from ost::IPV4Address. References ost::IPV4Address::operator=(). Friends And Related Function Documentation __EXPORT IPV4Host operator& (const IPV4Host &addr, const IPV4Mask &mask) [friend] Masks are usually used to coerce host addresses into a specific router or class domain. This can be done by taking the Inet Host Address object and 'and'ing it with an address mask. This operation can be directly expressed in C++ through the & operator. Returns: a internet host address that has been masked. Parameters: addr host address to be masked by subnet. mask inetnet mask address object to mask by.
