SetThreadPriorityBoost info  Overview  Group

The SetThreadPriorityBoost function disables the ability of Windows NT to temporarily boost the priority of a thread.

BOOL SetThreadPriorityBoost(

    HANDLE hThread,

// handle to thread

    BOOL DisablePriorityBoost

// priority boost control state

   );

Parameters

hThread
Handle to the thread whose priority is to be boosted. This thread must have the THREAD_SET_INFORMATION access right associated with it. For more information, see Thread Objects.
DisablePriorityBoost
A Boolean variable that is used to set the priority boost control state. A value of TRUE indicates that dynamic boosting is to be disabled. A value of FALSE restores normal behavior.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

When a thread is running in one of the dynamic priority classes, Windows NT temporarily boosts the thread’s priority when it is taken out of a wait state. If SetThreadPriorityBoost is called with the DisablePriorityBoost parameter set to TRUE, the thread’s priority is not boosted. To restore normal behavior, call SetThreadPriorityBoost with DisablePriorityBoost set to FALSE.
