ACCESSTIMEOUT info  Overview  Group

The ACCESSTIMEOUT structure contains information about the time-out period associated with the Win32 accessibility features. The accessibility time-out period is the length of time that must pass without keyboard and mouse input before the operating system automatically turns off accessibility features. The accessibility features affected by the time-out are the FilterKeys features (SlowKeys, BounceKeys, and RepeatKeys), MouseKeys, ToggleKeys, and StickyKeys. The accessibility time-out is designed for computers that are shared by several users so that options selected by one user do not inconvenience a subsequent user.

Windows 95: The accessibility time-out affects the High Contrast Mode setting.

typedef struct tagACCESSTIMEOUT {     // ato 

    UINT cbSize; 

    DWORD dwFlags; 

    DWORD iTimeOutMSec; 




Specifies the size, in bytes, of this structure.
A set of bit flags that specify properties of the time-out behavior for accessibility features. The following values are defined:




If this flag is set, the operating system plays a descending siren sound when the time-out period elapses and the accessibility features are turned off.


If this flag is set, you can set a time-out period for accessibility features. An application can retrieve this value, but cannot set it.


If this flag is set, a time-out period has been set for accessibility features. If this flag is not set, the features will not time out even though a time-out period is specified.

Specifies the time-out period, in milliseconds.


Use an ACCESSTIMEOUT structure when calling the SystemParametersInfo function with the uiAction parameter set to the SPI_GETACCESSTIMEOUT or SPI_SETACCESSTIMEOUT value. When using SPI_GETACCESSTIMEOUT, you must specify the cbSize member of the ACCESSTIMEOUT structure; the SystemParametersInfo function fills in the remaining members. Specify all structure members when using the SPI_SETACCESSTIMEOUT value.
