When you want to combine functions and concepts into one index, you
should index the functions with
@findex and index the concepts
@cindex, and use the
@syncodeindex command to
redirect the function index entries into the concept index.
@syncodeindex command takes two arguments; they are the name
of the index to redirect, and the name of the index to redirect it to.
The template looks like this:
@syncodeindex from to
For this purpose, the indices are given two-letter names:
@syncodeindex command before or shortly after the
end-of-header line at the beginning of a Texinfo file. For example,
to merge a function index with a concept index, write the
@syncodeindex fn cp
This will cause all entries designated for the function index to merge in with the concept index instead.
To merge both a variables index and a function index into a concept index, write the following:
@syncodeindex vr cp @syncodeindex fn cp
@syncodeindex command puts all the entries from the `from'
index (the redirected index) into the
@code font, overriding
whatever default font is used by the index to which the entries are
now directed. This way, if you direct function names from a function
index into a concept index, all the function names are printed in the
@code font as you would expect.
