|
.TP
|
|
.I \- device_info
|
|
pointer to XkbDeviceInfoRec in which to free items
|
|
.TP
|
|
.I \- which
|

mask of components of device_info to free
|
|
.TP
|
|
.I \- free_all
|
|
True => free everything, including device_info
|
|
.SH DESCRIPTION
|
|
.LP
|
|
If
|
|
.I free_all
|
|
is True, the
|
|
.I XkbFreeDeviceInfo
|
|
frees all components of
|
|
.I device_info
|
|
and the XkbDeviceInfoRec structure pointed to by
|
|
.I device_info
|
|
itself. If
|
|
.I free_all
|
|
is False, the value of
|
|
.I which
|
|
determines which subcomponents are freed.
|
|
.I which
|
|
is an inclusive OR of one or more of the values from Table 1. If
|
|
.I which
|
|
contains XkbXI_ButtonActionsMask, all button actions associated with
|
|
.I device_info
|
|
are freed,
|
|
.I device_info->btn_acts
|
|
is set to NULL, and
|
|
.I device_info->num_btns
|
|
is set to zero. If
|
|
.I which
|
|
contains all bits in XkbXI_IndicatorsMask, all XkbDeviceLedInfoRec structures associated with
|
|
.I device_info
|
|
are freed,
|
|
.I device_info->leds
|
|
is set to NULL, and
|
|
.I device_info->sz_leds
|
|
and
|
|
.I device_info->num_leds
|
|
are set to zero. If
|
|
.I which
|
|
contains XkbXI_IndicatorMapsMask, all indicator maps associated with
|
|
.I device_info
|
|
are cleared, but the number of LEDs and the leds structures themselves is preserved. If
|
|
.I which
|
|
contains XkbXI_IndicatorNamesMask, all indicator names associated with
|
|
.I device_info
|
|
are cleared, but the number of LEDs and the leds structures themselves is preserved. If
|
|
.I which
|
|
contains XkbXI_IndicatorStateMask, the indicator state associated with the
|
|
.I device_info
|
|
leds are set to zeros but the number of LEDs and the leds structures themselves is preserved.
