|
There are two indices into the the_indices array.
|
|
* read_index is the index that points to the list of index
|
|
entries that we will find if we ask for the list of entries for
|
|
this name.
|
|
* write_index is the index that points to the list of index entries
|
|
that we will add new entries to.
|
|
|
|
Initially, read_index and write_index are the same, but the
|
|
@syncodeindex and @synindex commands can change the list we add
|
|
entries to.
|
|
|
|
For example, after the commands
|
|
@cindex foo
|
|
@defindex ii
|
|
@synindex cp ii
|
|
@cindex bar
|
|
|
|
the cp index will contain the entry `foo', and the new ii
|
|
index will contain the entry `bar'. This is consistent with the
|
|
way texinfo.tex handles the same situation.
|
|
|
|
In addition, for each index, it is remembered whether that index is
|
|
a code index or not. Code indices have @code{} inserted around the
|
|
first word when they are printed with printindex. */
