|

|
.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.
