IAVIFile::Info

The Info method fills and returns an AVIFILEINFO structure with information about a file. Called when an application uses the AVIFileInfo function.

HRESULT Info (
  PAVISTREAM pf,       
  AVISTREAMINFO *pfi,  
  LONG lSize           
);
 

Parameters

pf

Address of the interface to a file.

pfi

Address of an application-defined buffer to contain file information.

lSize

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

Return Values

Returns the HRESULT defined by OLE.

Remarks

If the buffer allocated is too small for the structure, this 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)
