XkbGetStickyKeysOptions − Queries the current StickyKeys attributes for a keyboard device


Bool XkbGetStickyKeysOptions

(Display *display, unsigned int

device_spec, unsigned int *options_rtrn);


− display

connection to X server

− device_spec

device ID, or XkbUseCoreKbd

− options_rtrn

backfilled with StickyKeys option mask


The StickyKeys control has two options that can be accessed via the ax_options of an XkbControlsRec structure. The first option, TwoKeys, specifies whether StickyKeys should automatically turn off when two keys are pressed at the same time. This feature is useful for shared computers so people who do not want them do not need to turn StickyKeys off if a previous user left StickyKeys on. The second option, LatchToLock, specifies whether or not StickyKeys locks a modifier when pressed twice in a row.

XkbGetStickyKeysOptions requests the attributes of the StickyKeys control from the server, waits for a reply, and backfills options_rtrn with a mask indicating whether the individual StickyKeys options are on or off. Valid bits in options_rtrn are:


XkbGetStickyKeysOptions returns True if successful; if a compatible version of the Xkb extension is not available in the server XkbGetStickyKeysOptions returns False.



The XkbGetStickyKeysOptions function returns True if the request for the attributes of the StickyKeys control from the server was successful.


The XkbGetStickyKeysOptions function returns False if a compatible version of the Xkb extension is not available in the server.


The XkbControlsRec structure is defined as follows:

#define XkbMaxLegalKeyCode 255
#define XkbPerKeyBitArraySize ((XkbMaxLegalKeyCode+1)/8)
