NAME
       XkbResizeDeviceButtonActions  -  Allocate additional space
       for button actions in an XkbDeviceInfoRec structure

SYNOPSIS
       Status   XkbResizeDeviceButtonActions    (    device_info,
       new_total )
             XkbDeviceInfoPtr device_info;
             unsigned int new_total;

ARGUMENTS
       - device_info
              structure in which to allocate button actions

       - new_total
              new total number of button actions needed

DESCRIPTION
       XkbResizeDeviceButtonActions  reallocates space, if neces-
       sary, to make sure there is room for a total of  new_total
       button  actions  in  the  device_info  structure.  Any new
       entries allocated are zeroed. If successful,  XkbResizeDe-
       viceButtonActions  returns  Success. If new_total is zero,
       all button actions are deleted,  device_info->num_btns  is
       set  to zero, and device_info->btn_acts is set to NULL. If
       device_info is invalid or new_total is greater  than  255,
       BadValue  is  returned.  If  a  memory  allocation failure
       occurs, a BadAlloc is returned.

       Info.

STRUCTURES
       Information about X Input Extension devices is transferred
       between a client program and the Xkb extension in an  Xkb-
       DeviceInfoRec structure:

           typedef struct {
               char *               name;          /* name for device */
               Atom                 type;          /* name for class of devices */
               unsigned short       device_spec;   /* device of interest */
               Bool                 has_own_state; /* True=>this device has its own state */
               unsigned short       supported;     /* bits indicating supported capabilities */
               unsigned short       unsupported;   /* bits indicating unsupported capabilities */
               unsigned short       num_btns;      /* number of entries in btn_acts */
               XkbAction *          btn_acts;      /* button actions */
               unsigned short       sz_leds;       /* total number of entries in LEDs vector */
               unsigned short       num_leds;      /* number of valid entries in LEDs vector */
               unsigned short       dflt_kbd_fb;   /* input extension ID of default (core kbd) indicator */
               unsigned short       dflt_led_fb;   /* input extension ID of default indicator feedback */
               XkbDeviceLedInfoPtr  leds;          /* LED descriptions */
           } XkbDeviceInfoRec, *XkbDeviceInfoPtr;
