+pthread_win32_test_features_np(int mask)

+

+	This routine allows an application to check which

+	run-time auto-detected features are available within

+	the library.

+

+	The possible features are:

+

+		PTW32_SYSTEM_INTERLOCKED_COMPARE_EXCHANGE

+			Return TRUE if the native version of

+			InterlockedCompareExchange() is being used.

+		PTW32_ALERTABLE_ASYNC_CANCEL

+			Return TRUE is the QueueUserAPCEx package

+			QUSEREX.DLL is available and the AlertDrv.sys

+			driver is loaded into Windows, providing

+			alertable (pre-emptive) asyncronous threads

+			cancelation. If this feature returns FALSE

+			then the default async cancel scheme is in

+			use, which cannot cancel blocked threads.

+

+	Features may be Or'ed into the mask parameter, in which case

+	the routine returns TRUE if any of the Or'ed features would

+	return TRUE. At this stage it doesn't make sense to Or features

+	but it may some day.
