XkbSARedirectSetVModsMask(3)     XKB FUNCTIONS    XkbSARedirectSetVModsMask(3)



NAME
       XkbSARedirectSetVModsMask - Sets the vmods_mask0 and vmods_mask1 fields
       of act from vm

SYNOPSIS
       void XkbSARedirectSetVModsMask macro ( act, vm )
             XkbRedirectKeyAction act;
             unsigned int vm;

ARGUMENTS
       - act  action in which to set vmods

       - vm   new value for virtual modifier mask

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 defi-
       nitions specify conflicting values for a single modifier, the real mod-
       ifier 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 con-
       sists 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 cate-
       gorizes  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  for-
       mats.

       XkbSARedirectSetVModsMask  sets  the vmods_mask0 and vmods_mask1 fields
       of act from vm.
