XkbAllocDeviceInfo(3) XKB FUNCTIONS XkbAllocDeviceInfo(3) NAME XkbAllocDeviceInfo - Obtain an XkbDeviceInfoRec structure SYNOPSIS XkbDeviceInfoPtr XkbAllocDeviceInfo (unsigned int device_spec, unsigned int n_buttons, unsigned int sz_leds); ARGUMENTS device_spec device ID with which structure will be used n_buttons number of button actions to allocate space for sz_leds number of LED feedbacks to allocate space for DESCRIPTION XkbAllocDeviceInfo allocates space for an XkbDeviceInfoRec structure and initializes that structure's device_spec field with the device ID specified by device_spec. If n_buttons is nonzero, n_buttons XkbActions are linked into the XkbDeviceInfoRec structure and initialized to zero. If sz_leds is nonzero, sz_leds XkbDeviceLedInfoRec structures are also allocated and linked into the XkbDeviceInfoRec structure. If you request XkbDeviceLedIn- foRec structures be allocated using this request, you must initialize them explicitly, by using XkbAddDeviceLedInfo(3). STRUCTURES Information about X Input Extension devices is transferred between a client program and the Xkb extension in an XkbDeviceInfoRec structure: typedef struct { char * name; /* name for device */ Atom type; /* name for class of devices */ unsigned short device_spec; /* device of interest */ Bool has_own_state; /* True=>this device has its own state */ unsigned short supported; /* bits indicating supported capabilities */ unsigned short unsupported; /* bits indicating unsupported capabilities */ unsigned short num_btns; /* number of entries in btn_acts */ XkbAction * btn_acts; /* button actions */ unsigned short sz_leds; /* total number of entries in LEDs vector */ unsigned short num_leds; /* number of valid entries in LEDs vector */ unsigned short dflt_kbd_fb; /* input extension ID of default (core kbd) indicator */ unsigned short dflt_led_fb; /* input extension ID of default indicator feedback */ XkbDeviceLedInfoPtr leds; /* LED descriptions */ } XkbDeviceInfoRec, *XkbDeviceInfoPtr; typedef struct { unsigned short led_class; /* class for this LED device*/ unsigned short led_id; /* ID for this LED device */ unsigned int phys_indicators; /* bits for which LEDs physically present */ unsigned int maps_present; /* bits for which LEDs have maps in maps */ unsigned int names_present; /* bits for which LEDs are in names */ unsigned int state; /* 1 bit => corresponding LED is on */ Atom names[XkbNumIndicators]; /* names for LEDs */ XkbIndicatorMapRec maps; /* indicator maps for each LED */ } XkbDeviceLedInfoRec, *XkbDeviceLedInfoPtr; SEE ALSO XkbAddDeviceLedInfo(3) X Version 11 libX11 1.8.13 XkbAllocDeviceInfo(3)
