IltmmWMMutualExclusion::get_StreamCount

#include "ltmm.h"

C Syntax	HRESULT IltmmMutualExclusion_get_StreamCount(pMutualExclusion, pVal)
C++ Syntax	HRESULT get_StreamCount(pVal)

IltmmWMMutualExclusion *pMutualExclusion;	/* pointer to an interface */
long *pVal;	/* pointer to a variable */

Retrieves the total number of streams in the object's stream list.

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.

For more information, refer to the Microsoft documentation for IWMMutualExclusion::GetStreams .
