IAVIFile::GetStream
The GetStream method opens a stream by accessing it in a file. Called when an application
uses the AVIFileGetStream function.
HRESULT GetStream(
PAVIFILE pf,
|
| PAVISTREAM *ppStream,
|
| DWORD fccType,
|
| LONG lParam
|
| );
|
|
Parameters
pf
Address of the interface to a file.
ppStream
Address to contain a pointer to the interface to a stream.
fccType
Four-character code indicating the type of stream to locate.
lParam
Stream number.
Return Values
Returns the HRESULT defined by OLE.
Remarks
It is typically easier to implement this method by creating all of the stream
objects in advance by using the IAVIFile::Open method. Then, this method accesses the interface to the specified stream.
Remember to increment the reference count maintained by the AddRef method for the stream when this method is used.
For handlers written in C++, GetStream has the following syntax:
HRESULT GetStream(PAVISTREAM *ppStream,
DWORD fccType, LONG lParam);
