[in] PATTERNID patternId,
[in] REFIID riid,
[out] void **patternObject
);
Parameters
[in] patternId
Type: PATTERNID
The identifier of the control pattern. For a list of control pattern IDs, see Control Pattern Identifiers.
[in] riid
Type: REFIID
A reference to the IID of the interface to retrieve through ppv.

Return value

Remarks
It is recommended that you use the IID_PPV_ARGS macro, defined in Objbase.h, to package the riid and ppv parameters. This macro provides the correct IID based on the interface pointed to by the value in ppv, which eliminates the possibility of a coding error.
