The BeginWriting method initializes the writing process.
Syntax
HRESULT BeginWriting();
Parameters
This method takes no parameters.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
| Return code | Meaning |
| E_OUTOFMEMORY | There is not enough available memory. |
| E_UNEXPECTED | The method failed for an unspecified reason. |
Remarks
BeginWriting must be called before writing any samples. This method does not actually start writing, but initializes the process. Between this call and the call to EndWriting there can be no configuration changes to the writer.
EndWriting must be called to cleanly end the writing of the samples.
