IAVIStream::Info method (vfw.h)

The Info method fills and returns an AVISTREAMINFO structure with information about a stream. Called when an application uses the AVIStreamInfo function.

Syntax

HRESULT Info(
  AVISTREAMINFOW *psi,
  LONG           lSize
);

Parameters

psi

Pointer to an AVISTREAMINFO structure to contain stream information.

lSize

Size, in bytes, of the structure specified by psi.

Return value

Returns the HRESULT defined by OLE.

Remarks

If the buffer allocated is too small for the structure, the Info method should fail the call by returning AVIERR_BUFFERTOOSMALL. Otherwise, it should fill the structure and return its size.

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

HRESULT Info(AVIFILEINFO *psi, LONG lSize)
