XkbResizeDeviceButtonActions(3) 				   XKB FUNCTIONS				   XkbResizeDeviceButtonActions(3)

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  necessary, 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, XkbResizeDeviceButtonActions 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.

       To free an XkbDeviceInfoRec structure, use XkbFreeDeviceInfo.

STRUCTURES

       Information about X Input Extension devices is transferred between a client program and the Xkb extension in an XkbDeviceInfoRec 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;
