NAME
XkbOutOfRangeGroupInfo - Returns only the out-of-range processing infor-
mation from the group_info field of an XkbSymMapRec structure
SYNOPSIS

grp_inf
Xkb description of interest
DESCRIPTION
XkbOutOfRangeGroupInfo returns only the out-of-range processing informa-
tion 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 specifi-
cation 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 deter-
mines the treatment of out-of-range groups, use XkbKeyGroupInfo and Xk-
bOutOfRangeGroupInfo.
The keyboard controls contain a groups_wrap field specifying the han-
dling of illegal groups on a global basis. That is, when the user per-
forms an action 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 guarantee 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 us-
ing 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.
