The KeAreApcsDisabled routine returns whether the calling thread is within a critical region, which disables normal kernel APC delivery, or a guarded region, which disables all kernel APC delivery.
KeAreApcsDisabled returns TRUE if the thread is within a critical region or a guarded region, and FALSE otherwise.
A thread running at IRQL = PASSIVE_LEVEL can use KeAreApcsDisabled to determine if normal kernel APCs are disabled. A thread that is inside a critical region has both user APCs and normal kernel APCs disabled, but not special kernel APCs. A thread that is inside a guarded region has all APCs disabled, including special kernel APCs.
