Use This call allows programs to specify how long the machine should be left idle for before it enters suspend mode (via [[Portable_Stop]]). h4. Notes SWI [[Portable_ReadFeatures]] can be used to determine if suspend functionality is available. The machine will only automatically enter suspend mode if the screen saver is active; therefore if the suspend time specified here is lower than the screen saver delay time, the suspend will be postponed until the screensaver starts. See also [[*FreezeTime]] which allows the delay (in units of seconds) to be specified via a *Command. h4. See also * [[Portable_Stop]] * [[Portable_ReadFeatures]] * [[*FreezeTime]]
