teOptIndex - Option Index and Enumeration

This enum defines the complete set of options, both user specified and automatically provided. This can be used, for example, to distinguish which of the equivalenced options was actually used.

switch (pOptDesc->optActualIndex) {
case INDEX_OPT_FIRST:
    stuff;
case INDEX_OPT_DIFFERENT:
    different-stuff;
default:
    unknown-things;
}
