.SH DESCRIPTION
|
||
|
|
.LP
|
||
|
|
.I XkbAllocDeviceInfo
|
||
|
|
allocates space for an XkbDeviceInfoRec structure and initializes that structure's
|
||
|
|
.I device_spec
|
||
|
|
field with the device ID specified by
|
||
|
|
.I device_spec.
|
||
|
|
If
|
||
|
|
.I n_buttons
|
||
|
|
is nonzero,
|
||
|
|
.I n_buttons
|
||
|
|
XkbActions are linked into the XkbDeviceInfoRec structure and initialized to zero. If
|
||
|
|
.I sz_leds
|
||
|
|
is nonzero,
|
||
|
|
.I sz_leds
|
||
|
|
XkbDeviceLedInfoRec structures are also allocated and linked into the XkbDeviceInfoRec structure. If
|
||
|
|
you request XkbDeviceLedInfoRec structures be allocated using this request, you must initialize them
|
||
|
|
explicitly.
|
||
|
|
|
||
|
|
To obtain an XkbDeviceLedInfoRec structure, use
|
||
|
|
.I XkbAllocDeviceLedInfo.
