.SH DESCRIPTION
.LP
The
.I 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
.I 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.
.I XkbGetKeyModifierMap
sends a request to the server for the modifier mappings for
.I num
keys starting with the key whose keycode is
.I first.
It waits for a reply and places the results in the
.I xkb->map->modmap
array. If successful,
.I XkbGetKeyModifier
returns Success.
If the map component of the
.I xkb
parameter has not been allocated,
.I 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,
.I XkbGetKeySyms
returns BadAccess. If any allocation errors occur while obtaining the modifier
map,
.I XkbGetKeyModifierMap
returns BadAlloc.
.SH DIAGNOSTICS
.TP 15
.B BadAccess
The Xkb extension has not been properly initialized
.TP 15
.B BadAlloc
Unable to allocate storage
