(Abstract) Determine the requirements for the output stream
protected abstract int InternalGetOutputSizeInfo(
int dwOutputStreamIndex,
out int pcbSize,
out int pcbAlignment
);
int dwOutputStreamIndex,
out int pcbSize,
out int pcbAlignment
);
Parameters
- dwOutputStreamIndex
- Output stream number
- pcbSize
- The minimum size of an output buffer for this stream, in bytes
- pcbAlignment
- The required buffer alignment, in bytes. If the output stream has no alignment requirement, the value is 1.
Return Value
S_OK to indicate successful operation.
Remarks
This method is called by the abstract class. You should never return zero for the alignment.
