NAME

       XkbSARedirectVModsMask - Returns the vmods_mask0 and vmods_mask1 fields
       of act converted to an unsigned int

SYNOPSIS

       unsigned int XkbSARedirectVModsMask (XkbRedirectKeyAction act);

ARGUMENTS

       - act  action from which to extract vmods

DESCRIPTION

       Actions associated with  the  XkbRedirectKeyAction  structure  generate
       KeyPress  and KeyRelease events containing a keycode different from the
       key that was pressed or released.

       The type field for the XkbRedirectKeyAction structure should always  be
       XkbSA_RedirectKey.   Key  presses  cause  a  KeyPress event for the key
       specified by the new_key field instead of the  actual  key.  The  state
       reported  in this event reports the current effective modifiers changed
       as follows: any real modifiers selected by the mods_mask field are  set
       to  corresponding  values from the mods field. Any real modifiers bound
       to the virtual modifiers specified by the vmods_mask0  and  vmods_mask1
       fields are either set or cleared, depending on the corresponding values
       in the vmods0 and vmods1 fields.  If  the  real  and  virtual  modifier
       definitions  specify conflicting values for a single modifier, the real
       modifier definition has priority.

       Key releases cause a KeyRelease event for  the  key  specified  by  the
       new_key  field  instead  of  the  actual  key. The state for this event
       consists of the  effective  keyboard  modifiers  at  the  time  of  the
       release, changed as described previously.

       The  XkbSA_RedirectKey  action normally redirects to another key on the
       same device as the key that caused the event, unless that  device  does
       not  belong  to the input extension KeyClass, in which case this action
       causes an event on the  core  keyboard  device.  (The  input  extension
       categorizes devices by breaking them into classes. Keyboards, and other
       input devices with keys, are classified  as  KeyClass  devices  by  the
       input extension.)

       The   vmods_mask0   and   vmods_mask1  fields  actually  represent  one
       vmods_mask value. Xkb  provides  macros  to  convert  between  the  two
       formats.

       XkbSARedirectVModsMask  returns  the vmods_mask0 and vmods_mask1 fields
       of act converted to an unsigned int.
