VOID EnableIdleRoutine(
  FTG ftg,
  BOOL fEnable


[in] Function tag that identifies the idle routine to be enabled or disabled.


[in] Contains TRUE if the idle engine should enable the idle routine, or FALSE if it should disable it.

The following functions deal with the MAPI idle engine and with idle routines based on the FNIDLE function prototype:

Idle routine function



Changes the characteristics of a registered idle routine.


Removes a registered idle routine from the MAPI system.


Disables or re-enables a registered idle routine without removing it from the MAPI system.


Adds an idle routine to the MAPI system, with or without enabling it.


Shuts down the MAPI idle engine for the calling application.


Initializes the MAPI idle engine for the calling application.

   ChangeIdleRoutine, DeregisterIdleRoutine, and EnableIdleRoutine take as an input parameter the function tag returned by FtgRegisterIdleRoutine.

When all foreground tasks for the platform become idle, the MAPI idle engine calls the highest priority idle routine that is ready to execute. There is no guarantee of calling order among idle routines of the same priority.
