-.SH DESCRIPTION
-The
-.ZN XChangeKeyboardMapping
-function defines the symbols for the specified number of KeyCodes
-starting with first_keycode.
-The symbols for KeyCodes outside this range remain unchanged.
-The number of elements in keysyms must be:
-.LP
-.Ds
-num_codes * keysyms_per_keycode
-.De
-.LP
-The specified first_keycode must be greater than or equal to min_keycode
-returned by
-.ZN XDisplayKeycodes ,
-or a
-.ZN BadValue
-error results.
-In addition, the following expression must be less than or equal to
-max_keycode as returned by
-.ZN XDisplayKeycodes ,
-or a
-.ZN BadValue
-error results:
-.LP
-.Ds
-first_keycode + num_codes \- 1
-.De
-.LP
-KeySym number N, counting from zero, for KeyCode K has the following index
-in keysyms, counting from zero:
-.LP
-.Ds
-(K \- first_keycode) * keysyms_per_keycode + N
-.De
-.LP
-The specified keysyms_per_keycode can be chosen arbitrarily by the client
-to be large enough to hold all desired symbols.
-A special KeySym value of
-.ZN NoSymbol
-should be used to fill in unused elements
-for individual KeyCodes.
-It is legal for
-.ZN NoSymbol
-to appear in nontrailing positions
-of the effective list for a KeyCode.
-.ZN XChangeKeyboardMapping
-generates a
-.ZN MappingNotify
-event.
-.LP
-There is no requirement that the X server interpret this mapping.
-It is merely stored for reading and writing by clients.
-.LP
-.ZN XChangeKeyboardMapping
-can generate
-.ZN BadAlloc
-and
-.ZN BadValue
-errors.
-.LP
-The
-.ZN XGetKeyboardMapping
-function returns the symbols for the specified number of KeyCodes
-starting with first_keycode.
-The value specified in first_keycode must be greater than
-or equal to min_keycode as returned by
-.ZN XDisplayKeycodes ,
-or a
-.ZN BadValue
-error results.
-In addition, the following expression must be less than or equal
-to max_keycode as returned by
-.ZN XDisplayKeycodes :
-.LP
-.Ds
-first_keycode + keycode_count \- 1
-.De
-.LP
-If this is not the case, a
-.ZN BadValue
-error results.
-The number of elements in the KeySyms list is:
-.LP
-.Ds
-keycode_count * keysyms_per_keycode_return
-.De
-.LP
-KeySym number N, counting from zero, for KeyCode K has the following index
-in the list, counting from zero:
-.Ds
-(K \- first_code) * keysyms_per_code_return + N
-.De
-.LP
-The X server arbitrarily chooses the keysyms_per_keycode_return value
-to be large enough to report all requested symbols.
-A special KeySym value of
-.ZN NoSymbol
-is used to fill in unused elements for
-individual KeyCodes.
-To free the storage returned by
-.ZN XGetKeyboardMapping ,
-use
-.ZN XFree .
-.LP
-.ZN XGetKeyboardMapping
-can generate a
-.ZN BadValue
-error.
-.LP
-The
-.ZN XDisplayKeycodes
-function returns the min-keycodes and max-keycodes supported by the
-specified display.
-The minimum number of KeyCodes returned is never less than 8,
-and the maximum number of KeyCodes returned is never greater than 255.
-Not all KeyCodes in this range are required to have corresponding keys.
-.LP
-The
-.ZN XSetModifierMapping
-function specifies the KeyCodes of the keys (if any) that are to be used
-as modifiers.
-If it succeeds,
-the X server generates a
-.ZN MappingNotify
-event, and
-.ZN XSetModifierMapping
-returns
-.ZN MappingSuccess .
-X permits at most 8 modifier keys.
-If more than 8 are specified in the
-.ZN XModifierKeymap
-structure, a
-.ZN BadLength
-error results.
-.LP
-The modifiermap member of the
-.ZN XModifierKeymap
-structure contains 8 sets of max_keypermod KeyCodes,
-one for each modifier in the order
-.ZN Shift ,
-.ZN Lock ,
-.ZN Control ,
-.ZN Mod1 ,
-.ZN Mod2 ,
-.ZN Mod3 ,
-.ZN Mod4 ,
-and
-.ZN Mod5 .
-Only nonzero KeyCodes have meaning in each set,
-and zero KeyCodes are ignored.
-In addition, all of the nonzero KeyCodes must be in the range specified by
-min_keycode and max_keycode in the
-.ZN Display
-structure,
-or a
-.ZN BadValue
-error results.
-.LP
-An X server can impose restrictions on how modifiers can be changed,
-for example,
-if certain keys do not generate up transitions in hardware,
-if auto-repeat cannot be disabled on certain keys,
-or if multiple modifier keys are not supported.
-If some such restriction is violated,
-the status reply is
-.ZN MappingFailed ,
-and none of the modifiers are changed.
-If the new KeyCodes specified for a modifier differ from those
-currently defined and any (current or new) keys for that modifier are
-in the logically down state,
-.ZN XSetModifierMapping
-returns
-.ZN MappingBusy ,
-and none of the modifiers is changed.
-.LP
-.ZN XSetModifierMapping
-can generate
-.ZN BadAlloc
-and
-.ZN BadValue
-errors.
-.LP
-The
-.ZN XGetModifierMapping
-function returns a pointer to a newly created
-.ZN XModifierKeymap
-structure that contains the keys being used as modifiers.
-The structure should be freed after use by calling
-.ZN XFreeModifiermap .
-If only zero values appear in the set for any modifier,
-that modifier is disabled.
-.LP
-The
-.ZN XNewModifiermap
-function returns a pointer to
-.ZN XModifierKeymap
-structure for later use.
-.LP
-The
-.ZN XInsertModifiermapEntry
-function adds the specified KeyCode to the set that controls the specified
-modifier and returns the resulting
-.ZN XModifierKeymap
-structure (expanded as needed).
-.LP
-The
-.ZN XDeleteModifiermapEntry
-function deletes the specified KeyCode from the set that controls the
-specified modifier and returns a pointer to the resulting
-.ZN XModifierKeymap
-structure.
-.LP
-The
-.ZN XFreeModifiermap
-function frees the specified
-.ZN XModifierKeymap
-structure.
-.SH STRUCTURES
-The
-.ZN XModifierKeymap
-structure contains:
-.LP
-.Ds 0
-.TA .5i 2.5i
-.ta .5i 2.5i
-typedef struct {
- int max_keypermod; /\&* This server's max number of keys per modifier */
- KeyCode *modifiermap; /\&* An 8 by max_keypermod array of the modifiers */
-} XModifierKeymap;
-.De
-.SH DIAGNOSTICS
-.TP 1i
-.ZN BadAlloc
-The server failed to allocate the requested resource or server memory.
-.TP 1i
-.ZN BadValue
-Some numeric value falls outside the range of values accepted by the request.
-Unless a specific range is specified for an argument, the full range defined
-by the argument's type is accepted. Any argument defined as a set of
-alternatives can generate this error.
