CHandle Class

This class provides methods for creating and using a handle object.

class CHandle

A CHandle object can be used whenever a handle is required: the main difference is that the CHandle object will automatically be deleted.


Some API functions will use NULL as an empty or invalid handle, while others use INVALID_HANDLE_VALUE. CHandle only uses NULL and will treat INVALID_HANDLE_VALUE as a real handle. If you call an API which can return INVALID_HANDLE_VALUE, you should check for this value before calling CHandle::Attach or passing it to the CHandle constructor, and instead pass NULL.
