long Index;	/* index */
IltmmCaptureSubType **SubType;	/pointer to a pointer /

Retrieves the subtype at the specified index.

Parameter	Description
pCaptureSubTypes	Pointer to an IltmmCaptureSubTypes interface.
Index	Index of the subtype to retrieve. This is a zero-based index.

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.

This function will fail if the index is out or range. To find out the number of subtypes, call IltmmCaptureSubTypes::get_Count.

If the function succeeds, the user should release the interface pointer by calling the interface’s Release method.
