-description

The Write method writes data to a stream. Called when an application uses the AVIStreamWrite function.

-parameters

-param lStart

Starting sample or frame number to write.

-param lSamples

Number of samples to write.

-param lpBuffer

Pointer to the buffer for the data.

-param cbBuffer

Size, in bytes, of the buffer specified by lpBuffer.

-param dwFlags

Applicable flags. The AVIF_KEYFRAME flag is defined and indicates that this frame contains all the information needed for a complete image.

-param plSampWritten

Pointer to a buffer used to contain the number of samples written.

-param plBytesWritten

Pointer to a buffer that receives the number of bytes written.

- ps

Pointer to the interface to a stream.

-returns

Returns the HRESULT defined by OLE.

-remarks

For handlers written in C++, Write has the following syntax:

HRESULT Write(LONG lStart, LONG lSamples, LPVOID lpBuffer, 
    LONG cbBuffer, DWORD dwFlags, LONG *plSampWritten, 
    LONG *plBytesWritten);
