.TH XkbResizeDeviceButtonActions __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
.SH NAME
XkbResizeDeviceButtonActions \- Allocate additional space for button actions in an XkbDeviceInfoRec structure
.SH SYNOPSIS
.HP
.B Status XkbResizeDeviceButtonActions
.BI "(\^XkbDeviceInfoPtr " "device_info" "\^,"
.BI "unsigned int " "new_total" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- device_info
structure in which to allocate button actions
.TP
.I \- new_total
new total number of button actions needed
.SH DESCRIPTION
.LP
.I XkbResizeDeviceButtonActions
reallocates space, if necessary, to make sure there is room for a total of
.I new_total
button actions in the
.I device_info
structure. Any new entries allocated are zeroed. If successful,
.I XkbResizeDeviceButtonActions
returns Success. If
.I new_total
is zero, all button actions are deleted,
.I device_info->num_btns
is set to zero, and
.I device_info->btn_acts
is set to NULL. If
.I device_info
is invalid or
.I 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
.I XkbFreeDeviceInfo.
.SH STRUCTURES
.LP
Information about X Input Extension devices is transferred between a client program and the Xkb
extension in an XkbDeviceInfoRec structure:
.nf

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 */
