As you can imagine, I know the Neutrino Library Reference well, so I thought I’d add a caveat: there are a few files that document several variations on the same function. For example, lgamma(), lgamma_r(), lgammaf(), and lgammaf_r() are all in l/lgamma.html, and ThreadCtl() and ThreadCtl_r() are both in t/threadctl.html. If the script doesn’t find the function you asked for, try using the base name. It should be possible to extend the script to try some alternatives — an exercise for the reader, perhaps.

As a bonus, this script will work for any data structures and variables that have their own page in the Neutrino Library Reference.

The 6.5.0 docs are in an Infocenter that uses Eclipse plugins, so you’ll need a slightly different URL.
