Parameter |
Description |
|
pPlay |
Pointer to an IltmmPlay interface. |
|

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
Declare a long value equal to the bitwise-OR combination of the ltmmPlay_Seek attributes that you want to test. Pass this value in the Mask parameter. When the function returns, pCaps contains a subset of the original bits, indicating which capabilities are present. The return value indicates whether some, none, or all of the requested capabilities are present.
