Remarks

Typically, you use CComMultiThreadModel through one of two typedef names, either CComObjectThreadModel or CComGlobalsThreadModel. The class referenced by each typedef depends on the threading model used, as shown in the following table:

typedef	Single threading	Apartment threading	Free threading
CComObjectThreadModel	S	S	M
CComGlobalsThreadModel	S	M	M

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.
