Detailed Description

Root interface for all interfaces.

Member Function Documentation

virtual signed int IRoot::AskInterface ( const BGUID *  piid, IRoot **  ppr  )

pure virtual

Queries this object to see if the interface piid is supported and returns the result in ppr.

Parameters

piid	The BGUID of the requested interface.
ppr	The address of an IRoot pointer which will receive the new interface.

Returns

S_OK if the interface is supported. E_FAIL if it is not.

virtual signed int IRoot::DecRef ( )

pure virtual

Decreases the reference count on this object by 1. If the reference count reaches 0, the object is deallocated.

virtual signed int IRoot::IncRef ( )

pure virtual

Increases the reference count on this object by 1. You do not need to call this after an object is first created. It is 1 by default.
