// 
// Returns the memory region of the mapped file and type of its mapping. The choice of the file mapping type 
// for each scope is CLR implementation specific and user cannot explicitly set it.
// 
// The memory is valid only as long as the underlying MetaData scope is opened (there's a reference to 
// a MetaData interface for this scope).
// 
// Implements public API code:IMetaDataInfo::GetFileMapping.
// 
// Arguments:
//    ppvData - Fills with pointer to the start of the mapped file.
//    pcbData - Fills with the size of the mapped memory region (for flat-mapping it is the size of the 
//              file).
//    pdwMappingType - Fills with type of file mapping (code:CorFileMapping).
//        Current CLR implementation returns always code:fmFlat. The other value(s) are reserved for future 
//        usage. See code:StgIO::MapFileToMem#CreateFileMapping_SEC_IMAGE for more details.
// 
// Return Value:
//    S_OK               - All output data are filled.
//    COR_E_NOTSUPPORTED - CLR cannot (or doesn't want to) provide the memory region.
//        This can happen when:
//          - The MetaData scope was opened with flag code:ofWrite or code:ofCopyMemory.
//            Note: code:ofCopyMemory could be supported in future CLR versions. For example if we change 
//            code:CLiteWeightStgdbRW::OpenForRead to copy whole file (or add a new flag ofCopyWholeFile).
//          - The MetaData scope was opened without flag code:ofReadOnly.
//            Note: We could support this API without code:ofReadOnly flag in future CLR versions. We just 
//            need some test coverage and user scenario for it.
//          - Only MetaData part of the file was opened using code:OpenScopeOnMemory.
//          - The file is not NT PE file (e.g. it is NT OBJ = .obj file produced by managed C++).
//    E_INVALIDARG       - NULL was passed as an argument value.
