typedef

S=CComSingleThreadModel; M=CComMultiThreadModel

CComMultiThreadModel itself defines three typedef names. AutoCriticalSection and CriticalSection reference classes that provide methods for obtaining and releasing ownership of a critical section. ThreadModelNoCS references class CComMultiThreadModelNoCS.
