NAME

       XkbSAActionSetCtrls - Sets the ctrls0 through ctrls3 fields of act from ctrls

SYNOPSIS

       void XkbSAActionSetCtrls (XkbCtrlsAction act, unsigned int ctrls);

ARGUMENTS

       - act  action in which to set ctrls0-ctrls3

       - ctrls
	      value to set in ctrls0-ctrls3

DESCRIPTION

       Actions associated with the XkbCtrlsAction structure change the state of the boolean controls.

       The type field can have any one of the values shown in Table 1.

		       Table 1 Controls Action Types
       --------------------------------------------------------------
       Type		    Effect
       --------------------------------------------------------------
       XkbSA_SetControls    A key press enables any boolean controls
			    specified in the ctrls fields that	were
			    not  already  enabled at the time of the
			    key press.	A key release  disables  any
			    controls enabled by the key press.	This
			    action   can   cause   XkbControlsNotify
			    events.
       XkbSA_LockControls   If	the  XkbSA_LockNoLock bit is not set
			    in the flags field, a key press  enables
			    any  controls  specified  in  the  ctrls
			    fields that were not already enabled  at
			    the time of the key press.
			    If the XkbSA_LockNoUnlock bit is not set
			    in the flags field, a key  release	dis-
			    ables  any	controls  specified  in  the
			    ctrls fields that were not already	dis-
			    abled at the time of the key press.
			    This  action can cause XkbControlsNotify
			    events.

       The flags field is composed of the bitwise inclusive OR of the masks shown in Table 2.

		       Table 2 Control Action Flags
       --------------------------------------------------------------
       Flag		    Meaning
       --------------------------------------------------------------
       XkbSA_LockNoLock     If	set,  and   the   action   type   is
			    XkbSA_LockControls, the server only dis-
			    ables controls.
       XkbSA_LockNoUnlock   If	set,  and   the   action   type   is
			    XkbSA_LockControls,   the	server	only
			    enables controls.

       The XkbSA_SetControls action implements a key that enables a boolean control when pressed and disables it when released. The XkbSA_LockCon-
       trols  action  is  used to implement a key that toggles the state of a boolean control each time it is pressed and released. The XkbSA_Loc-
       kNoLock and XkbSA_LockNoUnlock flags allow modifying the toggling behavior to only unlock or only lock the boolean control.

       The ctrls0, ctrls1, ctrls2, and ctrls3 fields represent the boolean controls in the enabled_ctrls field	of  the  controls  structure.  Xkb
       macros, to convert between the two formats.

       XkbSAActionSetCtrls sets the ctrls0 through ctrls3 fields of act from ctrls.
