Parameter

Description

pMutualExclusion

Pointer to an IltmmWMMutualExclusion interface.

pVal

Pointer to a variable to be updated with the number of streams in the object's stream list.

Returns

S_OK

The function was successful.

<> S_OK

An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.

Comments

Using the number of streams as a zero based index, the IltmmWMMutualExclusion::GetStream function can then be used to get the stream numbers for each stream in the object's stream list.
