APTTYPEQUALIFIER_IMPLICIT_MTA constant
int
const APTTYPEQUALIFIER_IMPLICIT_MTA
This qualifier is only valid when the pAptType parameter of the CoGetApartmentType function specifies APTTYPE_MTA on return. A thread has an implicit MTA apartment type if it does not initialize the COM apartment itself, and if another thread has already initialized the MTA in the process. This qualifier informs the API caller that the MTA of the thread is implicitly inherited from other threads and is not initialized directly.
Implementation
static const APTTYPEQUALIFIER_IMPLICIT_MTA = 1;
