It must, however, indicate either the core keyboard or a valid X Input Extension +device. + +The +.I which +parameter is a mask specifying optional information to be returned. It is an inclusive OR of one or more of the values from +Table 1 and causes the returned XkbDeviceInfoRec to contain values for the corresponding fields specified in the table. + +.nf + Table 1 XkbDeviceInfoRec Mask Bits +____________________________________________________________________________________ +Name XkbDeviceInfoRec Value Capability If Set + Fields Effected +____________________________________________________________________________________ +XkbXI_KeyboardsMask (1L <<0) Clients can use all + Xkb requests and events + with KeyClass devices + supported by the input + device extension. + +XkbXI_ButtonActionsMask num_btns (1L <<1) Clients can assign key + btn_acts actions to buttons + non-KeyClass input + extension devices. + +XkbXI_IndicatorNamesMask leds->names (1L <<2) Clients can assign + names to indicators on + non-KeyClass input + extension devices. + +XkbXI_IndicatorMapsMask leds->maps (1L <<3) Clients can assign + indicator maps to + indicators on + non-KeyClass input + extension devices. + +XkbXI_IndicatorStateMask leds->state (1L <<4) Clients can request + the status of indicators + on non-KeyClass input + extension devices. + +XkbXI_IndicatorsMask sz_leds (0x1c) XkbXI_IndicatorNamesMask | + num_leds XkbXI_IndicatorMapsMask | + leds->* XkbXI_IndicatorStateMask + +XkbXI_UnsupportedFeaturesMask unsupported (1L <<15) + +XkbXI_AllDeviceFeaturesMask Those selected (0x1e) XkbXI_IndicatorsMask | + by Value Column XkbSI_ButtonActionsMask + masks + +XkbXI_AllFeaturesMask Those selected (0x1f) XkbSI_AllDeviceFeaturesMask | + by Value Column XkbSI_KeyboardsMask + masks + +XkbXI_AllDetailsMask Those selected (0x801f) XkbXI_AllFeaturesMask | + by Value column XkbXI_UnsupportedFeaturesMask + masks +.fi + +The XkbDeviceInfoRec returned by +.I XkbGetDeviceInfo +always has values for +.I name +(may be a null string, ""), +.I type, supported, unsupported, has_own_state, dflt_kbd_fd, +and +.I dflt_kbd_fb. +Other fields are filled in as specified by +.I which. + +Upon return, the +.I supported +field will be set to the inclusive OR of zero or more bits from Table 1; each bit set indicates an optional Xkb extension +device feature supported by the server implementation, and a client may modify the associated behavior. + +If the XkbButtonActionsMask bit is set in +.I which, +the XkbDeviceInfoRec returned will have the button actions +.I (btn_acts +field) filled in for all buttons. + +If +.I which +includes one of the bits in XkbXI_IndicatorsMask, the feedback class of the indicators must be specified in +.I ind_class, +and the feedback ID of the indicators must be specified in +.I ind_id. +If the request does not include any of the bits in XkbXI_IndicatorsMask, the +.I ind_class +and +.I ind_id +parameters are ignored. The class and ID can be obtained via the input device extension +.I XListInputDevices +request. + +If any of the XkbXI_IndicatorsMask bits are set in +.I which, +the XkbDeviceInfoRec returned will have filled in the portions of the +.I leds +structure corresponding to the indicator feedback identified by +.I ind_class +and +.I ind_id. +The +.I leds +vector of the XkbDeviceInfoRec is allocated if necessary and +.I sz_leds +and +.I num_leds +filled in. The +.I led_class, led_id +and +.I phys_indicators +fields of the +.I leds +entry corresponding to +.I ind_class +and +.I ind_id +are always filled in. If +.I which +contains XkbXI_IndicatorNamesMask, the +.I names_present +and +.I names +fields of the +.I leds +structure corresponding to +.I ind_class +and +.I ind_id +are returned. If +.I which +contains XkbXI_IndicatorStateMask, the corresponding +.I state +field is updated. If +.I which +contains XkbXI_IndicatorMapsMask, the +.I maps_present +and +.I maps +fields are updated. + +Xkb provides convenience functions to request subsets of the information available via +.I XkbGetDeviceInfo. +These convenience functions mirror some of the mask bits. The functions all take an XkbDeviceInfoPtr as an input argument +and operate on the X Input Extension device specified by the +.I device_spec +field of the structure. Only the parts of the structure indicated in the function description are updated.
