| <P><B>pthread_win32_test_features_np</B> allows an application to | |
| check which run-time auto-detected features are available within the | |

| <P><B>PTW32_SYSTEM_INTERLOCKED_COMPARE_EXCHANGE</B></P> | |
| <P STYLE="margin-left: 2cm">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().</P> | |

| <P STYLE="margin-left: 2cm">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.</P> | |
