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)
