XkbSARedirectVModsMask(3)		  XKB FUNCTIONS 		XkbSARedirectVModsMask(3)

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

SYNOPSIS
       unsigned int XkbSARedirectVModsMask macro ( act )
	     XkbRedirectKeyAction act;

ARGUMENTS
       - act  action from which to extract vmods

DESCRIPTION
       Actions associated with the XkbRedirectKeyAction structure generate  KeyPress  and  KeyRe-
       lease 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  corre-
       sponding  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 modi-
       fier definitions specify conflicting values for a single modifier, the real modifier defi-
       nition 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  Key-
       Class,  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 pro-
       vides macros to convert between the two formats.

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