XKB FUNCTIONS                    XkbGetDetectableAutoRepeat(3x11)



NAME
     XkbGetDetectableAutoRepeat - Determines whether or  not  the
     server supports DetectableAutoRepeat

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

     Bool  XkbGetDetectableAutoRepeat  (Display  *display,   Bool
          *supported_rtrn);

ARGUMENTS
     - display
          connection to X server

     - supported_rtrn
          backfilled True if DetectableAutoRepeat supported

DESCRIPTION
     Auto-repeat is the generation of multiple key  events  by  a
     keyboard when the user presses a key and holds it down. Key-
     board hardware and device-dependent X server software  often
     implement auto-repeat by generating multiple KeyPress events
     with no intervening KeyRelease event. The standard  behavior
     of  the X server is to generate a KeyRelease event for every
     KeyPress  event.  If  the  keyboard  hardware  and   device-
     dependent  software of the X server implement auto-repeat by
     generating multiple KeyPress events, the  device-independent
     part  of  the  X server by default synthetically generates a
     KeyRelease event after each KeyPress  event.  This  provides
     predictable behavior for X clients, but does not allow those
     clients to detect the fact that a key is auto-repeating.

     Xkb allows clients to request detectable auto-repeat.  If  a
     client   requests  and  the  server  supports  DetectableAu-
     toRepeat, Xkb generates KeyRelease events only when the  key
     is  physically released. If DetectableAutoRepeat is not sup-
     ported or has not been requested, the server  synthesizes  a
     KeyRelease  event  for each repeating KeyPress event it gen-
     erates.

     DetectableAutoRepeat, unlike other  controls,  is  not  con-
     tained  in  the  XkbControlsRec  structure,  nor  can  it be
     enabled  or  disabled  via  the   EnabledControls   control.
     Instead,  query  and  set DetectableAutoRepeat using XkbGet-
     DetectableAutoRepeat and XkbSetDetectableAutoRepeat.

     DetectableAutoRepeat is a condition that applies to all key-
     board devices for a client's connection to a given X server;
     it cannot be selectively set for some devices  and  not  for
     others.  For  this reason, none of the Xkb library functions
     involving DetectableAutoRepeat involve a device specifier.

XKB FUNCTIONS                    XkbGetDetectableAutoRepeat(3x11)



     XkbGetDetectableAutoRepeat  queries  the  server   for   the
     current state of DetectableAutoRepeat and waits for a reply.
     If supported_rtrn is not NULL, it  backfills  supported_rtrn
     with  True  if the server supports DetectableAutoRepeat, and
     False  otherwise.   XkbGetDetectableAutoRepeat  returns  the
     current  state  of  DetectableAutoRepeat  for the requesting
     client:  True if DetectableAutoRepeat is set, and False oth-
     erwise.

RETURN VALUES
     True           The    XkbGetDetectableAutoRepeat    function
                    returns  True if the server supports Detecta-
                    bleAutoRepeat.

     False          The    XkbGetDetectableAutoRepeat    function
                    returns  False if the server does not support
                    DetectableAutoRepeat.
