pthread_win32_test_features_np – +find out what features were detected at process attach time.

Synopsis

#include <pthread.h> +

BOOL pthread_win32_test_features_np(int mask);

Description

pthread_win32_test_features_np 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 Win32 version of +InterlockedCompareExchange() is being used. On IA32 systems the +library can use optimised and inlinable assembler versions of +InterlockedExchange() and InterlockedCompareExchange().

PTW32_ALERTABLE_ASYNC_CANCEL

Return TRUE if the QueueUserAPCEx package +QUSEREX.DLL and the AlertDrv.sys driver was detected. This package +provides alertable (pre-emptive) asynchronous threads cancellation. +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.
