IMediaSeeking::IsUsingTimeFormat
The IsUsingTimeFormat method determines whether seek operations are currently using a specified time format.
Syntax
HRESULT IsUsingTimeFormat( const GUID *pFormat );
Parameters
pFormat
[in] Pointer to a GUID that specifies the time format. See Time Format GUIDs.
Return Values
Returns an HRESULT value. Possible values include the following.
| Return code | Description |
| S_FALSE | The specified format is not the current format. |
| S_OK | The specified format is the current format. |
| E_NOTIMPL | Not implemented. |
| E_POINTER | NULL pointer argument. |
Remarks
This method is slightly more efficient than the IMediaSeeking::GetTimeFormat method, because it does not require copying the GUID.
Requirements
Header: Declared in Strmif.h; include Dshow.h.
Library: Use Strmiids.lib.
