IAsyncReader::SyncReadAligned (Windows CE 5.0)
This method performs a synchronous read of the data.
HRESULT SyncReadAligned(IMediaSample* pSample);
Parameters
- pSample
Sample to read.
Return Values
Returns an HRESULT value that depends on the implementation of the interface. Current DirectShow implementation return values include the following.
| Value | Description |
|---|---|
| VFW_E_BADALIGN | An invalid alignment was specified. |
| HRESULT_FROM_WIN32 | Win32 error. |
| S_FALSE | Size changed (probably due to end of file). |
| S_OK | Success. |
Remarks
The sample passed in must have been acquired from the agreed allocator. The start and stop positions must be aligned equivalent to an IAsyncReader::Request/IAsyncReader::WaitForNext pair, but may avoid the need for a thread on the source filter.
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.
OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
