IResourceManager::Register method (strmif.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The Register
method registers a single named resource with the resource manager.
Syntax

[in] LPCWSTR pName,
[in] LONG cResource,
[out] LONG *plToken
);
Parameters
[in] pName
Named resource.
[in] cResource
Number of resources.
[out] plToken
Pointer to the returned token identifying the resource to be used in additional calls.
Return value

Remarks
This method registers a named resource, which can contain a number of resources, and returns a token to be used when requesting this resource. It is not an error if the resource is already registered; if the number in the cResource parameter is less than what is already registered, resources will be deallocated to the new count. To unregister the resource, pass a count of zero in cResource.
