Opens an existing file from disk, and maps its metadata into memory for importing (reading).
The name of the file to be opened. The file must contain common language runtime (CLR) metadata.
Specifies the mode (read, and so on) for opening. This is a value of the CorOpenFlags enumeration. You can only import (read) from the file, not emit (write) to it.
The IID of the desired metadata interface to be returned; the caller will use the interface to import (read) metadata.
Valid values for riid include IID_IUnknown, IID_IMetaDataImport, IID_IMetaDataImport2, IID_IMetaDataAssemblyImport, IID_IMetaDataTables, and IID_IMetaDataTables2.
The pointer to the returned interface.
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
The in-memory copy of the metadata can be queried using methods from one of the "import" interfaces. If the target file doesn't contain CLR metadata, then the OpenScope method will fail.
