XkbOutOfRangeGroupNumber(3)	  XKB FUNCTIONS      XkbOutOfRangeGroupNumber(3)

NAME
     XkbOutOfRangeGroupNumber  -  Returns  the out-of-range group number, repre-
     sented as a group index, from  the  group_info  field  of	an  XkbSymMapRec
     structure

SYNOPSIS
     unsigned char XkbOutOfRangeGroupNumber (unsigned char grp_inf);

ARGUMENTS
     grp_inf
	    Xkb description of interest

DESCRIPTION
     XkbOutOfRangeGroupNumber returns the out-of-range group number, represented
     as a group index, from the group_info field of an XkbSymMapRec structure.

     The  group_info field of an XkbSymMapRec is an encoded value containing the
     number of groups of symbols bound to the key as well as  the  specification
     of the treatment of out-of-range groups. It is legal for a key to have zero
     groups, in which case it also has zero symbols and all events from that key
     yield  NoSymbol.	To  obtain  the number of groups of symbols bound to the
     key, use XkbKeyNumGroups.	To change the number of groups bound to  a  key,
     use XkbChangeTypesOfKey.  To obtain a mask that determines the treatment of
     out-of-range groups, use XkbKeyGroupInfo and XkbOutOfRangeGroupInfo.

     The  keyboard  controls contain a groups_wrap field specifying the handling
     of illegal groups on a global basis. That is, when the user performs an ac-
     tion causing the effective  group	to  go	out  of  the  legal  range,  the
     groups_wrap  field  specifies how to normalize the effective keyboard group
     to a group that is legal for the keyboard as a whole, but there is no guar-
     antee that the normalized group will be within the range  of  legal  groups
     for  any  individual  key. The per-key group_info field specifies how a key
     treats a legal effective group if the key does not have  a  type  specified
     for  the  group of concern. For example, the Enter key usually has just one
     group defined. If the user performs an action causing the	global	keyboard
     group to change to Group2, the group_info field for the Enter key describes
     how to handle this situation.

     Out-of-range  groups  for individual keys are mapped to a legal group using
     the same options as are used for the overall keyboard group. The particular
     type of mapping used is controlled by the bits set in the group_info  flag,
     as shown in Table 1.
