NAME
       XkbSAPtrDfltValue - Returns the valueXXX field of act con-
       verted to a signed int

SYNOPSIS
       int XkbSAPtrDfltValue macro ( act )
             XkbAction act;

ARGUMENTS
       - act  action from which to extract group

DESCRIPTION
       Actions associated  with  the  XkbPtrDfltAction  structure
       change the mk_dflt_btn attribute of the MouseKeys control.

       If the MouseKeys control  is  not  enabled,  KeyPress  and
       KeyRelease  events  are  treated  as  though the action is
       XkbSA_NoAction.  Otherwise,  this   action   changes   the
       mk_dflt_btn attribute of the MouseKeys control.

       The  type  field  of the XkbPtrDfltAction structure should
       always be XkbSA_SetPtrDflt.

       The flags field is composed of the bitwise inclusive OR of
       the  values  shown in Table 1 (currently there is only one
       value defined).

                        Table 1 Pointer Default Flags
       -----------------------------------------------------------------
       Flag                    Meaning
       -----------------------------------------------------------------
       XkbSA_DfltBtnAbsolute   If set, the value  field  represents  an
                               absolute  pointer button. Otherwise, the
                               value field represents the amount to  be
                               added to the current default button.

       The  affect  field  specifies  what changes as a result of
       this action. The only valid value for the affect field  is
       XkbSA_AffectDfltBtn.

       The  valueXXX  field is a signed character that represents
       the new button value for the mk_dflt_btn attribute of  the
       MouseKeys  control.  If  XkbSA_DfltBtnAbsolute  is  set in
       flags, valueXXX specifies the button to  be  used;  other-
       wise,  valueXXX  specifies  the  amount to be added to the
       current default button. In  either  case,  illegal  button
       choices  are  wrapped back around into range. Xkb provides
       macros, to convert between the integer and signed  charac-
       ter values in XkbPtrDfltAction structures.

       XkbSAPtrDfltValue  returns  the valueXXX field of act con-
       verted to a signed int.

STRUCTURES

               unsigned char    type;      /* XkbSA_SetPtrDflt */
               unsigned char    flags;     /* controls the pointer button number */
               unsigned char    affect;    /* XkbSA_AffectDfltBtn */
               char             valueXXX;  /* new default button member */
           } XkbPtrDfltAction;
