`@syncodeindex'
---------------
When you want to combine functions and concepts into one index, you
should index the functions with `@findex' and index the concepts with
`@cindex', and use the `@syncodeindex' command to redirect the function
index entries into the concept index.
The `@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:
`cp'
concept index
`fn'
function index
`vr'
variable index
`ky'
key index
`pg'
program index
`tp'
data type index
Write an `@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 following:
@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
The `@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.
