[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The Reserve method reserves or unreserves a device resource.
Flag indicating whether to reserve or unreserve this device. The value must be a member of the AMRESCTL_RESERVEFLAGS enumeration.
Must be NULL.
Returns S_OK if the device was successfully reserved or unreserved, S_FALSE if the device is currently reserved and will continue to be held, or an HRESULT error code if the device can't be reserved.
A resource can be reserved multiple times. If the method returns S_OK, the filter increments an internal reserve count. For every call to reserve a device that returns S_OK, the caller must make a matching call to unreserve the device.
