IAMDevMemoryControl::QueryWriteSync

  • Note   The IAMDevMemoryControl interface is deprecated.

Checks if the memory supported by the allocator requires the use of the IAMDevMemoryControl::WriteSync method.

Syntax

  HRESULT QueryWriteSync(void);

Return Value

Returns S_OK if the method is required, or S_FALSE otherwise.

Remarks

Not all on-board memory needs to have WriteSync called to synchronize with the completed write. This method is used to check if the call is necessary.

Requirements

Reference: Dshow.h.

Library: Quartz.dll.
