Microsoft DirectX 9.0


The QueryAccept method determines whether the pin accepts a specified media type. This method implements the IPin::QueryAccept method.


HRESULT QueryAccept(
    const AM_MEDIA_TYPE *pmt



Pointer to an AM_MEDIA_TYPE structure that specifies the media type.

Return Value

Returns S_OK if the media type is acceptable. Otherwise, returns S_FALSE.


In the base class, this method delegates to the CBasePin::CheckMediaType method. If CheckMediaType fails, QueryAccept returns S_FALSE.

This method does not hold the pin's critical section (CBasePin::m_pLock). If your derived class dynamically modifies the set of acceptable media types, you should override this method to hold the critical section.
