SYNOPSIS¶
Status
XkbGetKeyModifierMap (Display *dpy, unsigned int
first, unsigned int num, XkbDescPtr
xkb);

- - dpy
- connection to X server
- - first
- keycode of first key to get
- - num
- number of keys for which information is desired
- - xkb
- keyboard description to update
DESCRIPTION¶
The
modmap entry of the client map is an array, indexed by keycode,
specifying the real modifiers bound to a key. Each entry is a mask composed of
a bitwise inclusive OR of the legal real modifiers: ShiftMask, LockMask,
ControlMask, Mod1Mask, Mod2Mask, Mod3Mask, Mod4Mask, and Mod5Mask. If a bit is
set in a
modmap entry, the corresponding key is bound to that modifier.
Pressing or releasing the key bound to a modifier changes the modifier set and
unset state. The particular manner in which the modifier set and unset state
changes is determined by the behavior and actions assigned to the key.
XkbGetKeyModifierMap sends a request to the server for the modifier
mappings for
num keys starting with the key whose keycode is
first. It waits for a reply and places the results in the
xkb->map->modmap array. If successful,
XkbGetKeyModifier
returns Success.
If the map component of the
xkb parameter has not been allocated,
XkbGetKeyModifierMap allocates and initializes it.
If a compatible version of Xkb is not available in the server or the Xkb
extension has not been properly initialized,
XkbGetKeySyms returns
BadAccess. If any allocation errors occur while obtaining the modifier map,
XkbGetKeyModifierMap returns BadAlloc.
DIAGNOSTICS¶
- BadAccess
- The Xkb extension has not been properly initialized
- BadAlloc
- Unable to allocate storage
