-.TH XkbKeyActionsPtr __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
-.SH NAME
-XkbKeyActionsPtr \- Returns a pointer to the two-dimensional array of key
-actions associated with
-the key corresponding to keycode
-.SH SYNOPSIS
-.HP
-.B XkbKeyActionPtr XkbKeyActionsPtr
-.BI "(\^XkbDescPtr " "xkb" "\^,"
-.BI "KeyCode " "keycode" "\^);"
-.if n .ti +5n
-.if t .ti +.5i
-.SH ARGUMENTS
-.TP
-.I \- xkb
-Xkb description of interest
-.TP
-.I \- keycode
-keycode of interest
-.SH DESCRIPTION
-.LP
-A key action defines the effect key presses and releases have on the internal
-state of the server.
-For example, the expected key action associated with pressing the Shift key is
-to set the Shift
-modifier. There is zero or one key action associated with each keysym bound to
-each key.
-
-Just as the entire list of key symbols for the keyboard mapping is held in the
-.I syms
-field of the client map, the entire list of key actions for the keyboard mapping
-is held in the
-.I acts
-array of the server map. The total size of
-.I acts
-is specified by
-.I size_acts,
-and the number of entries is specified by
-.I num_acts.
-
-The
-.I key_acts
-array, indexed by keycode, describes the actions associated with a key. The
-.I key_acts
-array has
-.I min_key_code
-unused entries at the start to allow direct indexing using a keycode. If a
-.I key_acts
-entry is zero, it means the key does not have any actions associated with it. If
-an entry is not
-zero, the entry represents an index into the
-.I acts
-field of the server map, much as the
-.I offset
-field of a KeySymMapRec structure is an index into the
-.I syms
-field of the client map.
-
-The reason the
-.I acts
-field is a linear list of XkbActions is to reduce the memory consumption
-associated with a keymap.
-Because Xkb allows individual keys to have multiple shift levels and a different
-number of groups per
-key, a single two-dimensional array of KeySyms would potentially be very large
-and sparse. Instead,
-Xkb provides a small two-dimensional array of XkbActions for each key. To store
-all of these
-individual arrays, Xkb concatenates each array together in the
-.I acts
-field of the server map.
-
-The key action structures consist only of fields of type char or unsigned char.
-This is done to
-optimize data transfer when the server sends bytes over the wire. If the fields
-are anything but
-bytes, the server has to sift through all of the actions and swap any nonbyte
-fields. Because they
-consist of nothing but bytes, it can just copy them out.
-
-.I XkbKeyActionsPtr
-returns a pointer to the two-dimensional array of key actions associated with
-the key corresponding
-to
-.I keycode.
-Use
-.I XkbKeyActionsPtr
-only if the key actually has some actions associated with it, that is,
-.I XkbKeyNumActions
-(xkb, keycode) returns something greater than zero.
-.SH STRUCTURES
-.LP
-The KeySymMapRec structure is defined as follows:
-.nf
-
- #define XkbNumKbdGroups 4
- #define XkbMaxKbdGroup (XkbNumKbdGroups-1)
-
- typedef struct { /\(** map to keysyms for a single keycode
-*/
- unsigned char kt_index[XkbNumKbdGroups]; /\(** key type index for
-each group */
- unsigned char group_info; /\(** # of groups and out of range group
-handling */
- unsigned char width; /\(** max # of shift levels for key */
- unsigned short offset; /\(** index to keysym table in syms array
-*/
-} XkbSymMapRec, *XkbSymMapPtr;
