Public Interface:
|
|
|
|
CIPAddress : Various constructors
|
|
|
|
operator = : Assignment operator
|
|
operator == : Comparison operators
|
|
operator const DWORD : Cast operator
|
|
operator LPCTSTR : Cast operator
|
|
operator CString : Cast operator
|
|
CompareItem : Comparison function
|
|
QueryIPAddress : Get the ip address value
|
|
QueryNetworkOrderIPAddress : Get the ip address value (network order)
|
|
QueryHostOrderIPAddress : Get the ip address value (host order)
|
|
|
|
StringToLong : Convert ip address string to 32 bit number
|
|
LongToString : Convert 32 bit value to ip address string
