+BOOL
+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.
