NAME
XkbResizeDeviceButtonActions - Allocate additional space for button actions in an XkbDeviceInfoRec structure SYNOPSIS Status XkbResizeDeviceButtonActions (XkbDeviceInfoPtr deviceinfo, unsigned int newtotal); ARGUMENTS
- deviceinfo structure in which to allocate button actions
- newtotal new total number of button actions needed DESCRIPTION XkbResizeDeviceButtonActions reallocates space, if necessary, to make sure there is room for a total of newtotal button actions in the deviceinfo structure. Any new entries allocated are zeroed. If suc‐ cessful, XkbResizeDeviceButtonActions returns Success. If newtotal is
zero, all button actions are deleted, deviceinfo->numbtns is set to
zero, and deviceinfo->btnacts is set to NULL. If deviceinfo is invalid or newtotal is greater than 255, BadValue is returned. If a memory allocation failure occurs, a BadAlloc is returned. To free an XkbDeviceInfoRec structure, use XkbFreeDeviceInfo.
