IltmmWMProfile::GetStreamByNumber

#include "ltmm.h"

C Syntax	HRESULT IltmmWMProfile__getStreamByNumber(pProfile, StreamNum, pVal)
C++ Syntax	HRESULT GetStreamByNumber(StreamNum, pVal)

IltmmWMProfile *pProfile;	/* pointer to an interface */
long StreamNum;	/* stream number */
IltmmWMStreamConfig **pVal;	/* pointer to a pointer */

Gets the stream, with the specified number, in the profile.

Parameter	Description
pProfile	Pointer to an IltmmWMProfile interface.
StreamNum	The number of the stream to retrieve.
pVal	Pointer to a variable to be updated with a pointer to an IltmmWMStreamConfig interface. This interface will reference the retrieved stream.

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

The stream number is different from the stream index. Stream indexes are zero-based, while each stream in the list might have its own number that is different from the index. If the function succeeds, the caller must free the retrieved interface by calling its Release function.
