When your application receives a XkbNamesNotify event, you can note the changed names in a changes structure using XkbNoteNameChanges.
The wanted parameter is the bitwise inclusive OR of the valid names mask bits shown in Table 1. XkbNoteNameChanges copies any changes that are reported in new and specified in wanted into the changes record specified by old.
