Contains information about the time-out period associated with the Microsoft 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 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.
The accessibility features affected by the time-out are the FilterKeys features (SlowKeys, BounceKeys, and RepeatKeys), MouseKeys, ToggleKeys, and StickyKeys. The accessibility time-out also affects the high contrast mode setting.
Syntax
typedef struct tagACCESSTIMEOUT {
UINT cbSize;
DWORD dwFlags;
DWORD iTimeOutMSec;
} ACCESSTIMEOUT, *LPACCESSTIMEOUT;
Members
cbSize
Type: UINT
Specifies the size, in bytes, of this structure.
dwFlags
Type: DWORD
A set of bit flags that specify properties of the time-out behavior for accessibility features. The following values are defined.
iTimeOutMSec
Type: DWORD
Specifies the time-out period, in milliseconds.
Remarks
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.
