Xkb allows applications to obtain information about indicators using two
different methods. The first method, which is similar to the core X
implementation, uses a mask to specify the indicators. The second method, which
is more suitable for applications concerned with interoperability, uses
indicator names. The correspondence between the indicator name and the bit
position in masks is as follows: one of the parameters returned from
XkbGetNamedIndicators is an index that is the bit position to use in any function call that requires a
mask of indicator bits, as well as the indicators index into the
XkbIndicatorRec array of indicator maps.
XkbGetIndicatorMap obtains the maps from the server for only those indicators specified by the
which mask and copies the values into the keyboard description specified by
desc. If the
indicators field of the
desc parameter is NULL,
XkbGetIndicatorMap allocates and initializes it.
To free the indicator maps, use
