.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:
