SetProcessPriorityBoost

The SetProcessPriorityBoost function disables the ability of the system to temporarily boost the priority of the threads of the specified process.

BOOL SetProcessPriorityBoost(
  HANDLE hProcess,           // handle to process
  BOOL DisablePriorityBoost  // priority boost state
);

Parameters

hProcess

[in] Handle to the process. This handle must have the PROCESS_SET_INFORMATION access right. For more information, see Process Security and Access Rights.

DisablePriorityBoost

[in] Specifies 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, the system temporarily boosts the thread's priority when it is taken out of a wait state. If SetProcessPriorityBoost is called with the DisablePriorityBoost parameter set to TRUE, its threads' priorities are not boosted. This setting affects all existing threads and any threads subsequently created by the process. To restore normal behavior, call SetProcessPriorityBoost with DisablePriorityBoost set to FALSE.

Requirements

  Windows NT/2000: Requires Windows NT 4.0 or later.
  Windows 95/98: Unsupported.
  Header: Declared in Winbase.h; include Windows.h.
  Library: Use Kernel32.lib.
