NAME

6       XkbResizeDeviceButtonActions - Allocate additional space for button ac‐
7       tions in an XkbDeviceInfoRec structure
8

SYNOPSIS

10       Status XkbResizeDeviceButtonActions (XkbDeviceInfoPtr device_info,  un‐
11              signed int new_total);
12

ARGUMENTS

14       - device_info
15              structure in which to allocate button actions
16
17       - new_total
18              new total number of button actions needed
19

DESCRIPTION

21       XkbResizeDeviceButtonActions  reallocates  space, if necessary, to make
22       sure there is room for a total of new_total button actions in  the  de‐
23       vice_info  structure. Any new entries allocated are zeroed. If success‐
24       ful, XkbResizeDeviceButtonActions  returns  Success.  If  new_total  is
25       zero,  all  button actions are deleted, device_info->num_btns is set to
26       zero, and device_info->btn_acts is set to NULL. If device_info  is  in‐
27       valid or new_total is greater than 255, BadValue is returned. If a mem‐
28       ory allocation failure occurs, a BadAlloc is returned.

STRUCTURES

33       Information about X Input Extension devices is  transferred  between  a
34       client program and the Xkb extension in an XkbDeviceInfoRec structure:
35
36           typedef struct {
37               char *               name;          /∗ name for device */
38               Atom                 type;          /∗ name for class of devices */
39               unsigned short       device_spec;   /∗ device of interest */
40               Bool                 has_own_state; /∗ True=>this device has its own state */
41               unsigned short       supported;     /∗ bits indicating supported capabilities */
42               unsigned short       unsupported;   /∗ bits indicating unsupported capabilities */
43               unsigned short       num_btns;      /∗ number of entries in btn_acts */
44               XkbAction *          btn_acts;      /∗ button actions */
45               unsigned short       sz_leds;       /∗ total number of entries in LEDs vector */
46               unsigned short       num_leds;      /∗ number of valid entries in LEDs vector */
47               unsigned short       dflt_kbd_fb;   /∗ input extension ID of default (core kbd) indicator */
48               unsigned short       dflt_led_fb;   /∗ input extension ID of default indicator feedback */
49               XkbDeviceLedInfoPtr  leds;          /∗ LED descriptions */
50           } XkbDeviceInfoRec, *XkbDeviceInfoPtr;
