XKB FUNCTIONS                            XkbAllocDeviceInfo(3x11)



NAME
     XkbAllocDeviceInfo - Obtain an XkbDeviceInfoRec structure

SYNOPSIS
     cc [ flag... ] file... -lX11 [ library... ]

     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 XkbDevi-
     ceInfoRec 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  XkbDeviceLedInfoRec  structures  be  allocated
     using this request, you must initialize them explicitly.

     To obtain an XkbDeviceLedInfoRec structure, use XkbAllocDev-
     iceLedInfo.

STRUCTURES
     Information about X Input Extension devices  is  transferred
     between a client program and the Xkb extension in an XkbDev-
     iceInfoRec 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 */
