I have written a program which not only creates function prototypes of a file (or all files in a dir), but can also list all the functions, allow you to copy the source, proto, or call to 1 or many functions and also to compare different functions. This isn't exactly an add-in, but it integrates well with PellesC. It also has a text-only mode (command line parm: /x, use /? to see all), which can allow you to list functions within the Pelles output tab.
There's no help as yet.. If people are keen, I'll write some.
To get it (and other freeware), see my site at:
http://lingo.atspace.com/pro2.htmlTo integrate into PellesC - textmode was a little difficult, it took a little hack.
Specifically, in the customize tool dlg - edit tool.
You specify path and name of tool (p2.exe)
Arguments: -x ${FilePath}
Initial dir: whatever
Then, you need to click "Use Output Tab", however this is greyed out, because PellesC sees P2.exe as a GUI app, and thinks it can't use text output. You need to use a program such as WinSpy (freeware) to un-grey the checkbox, then you can select it and click ok. This worked ok for me.
To use it non-text mode, do as above except omit the -x and don't worry about the "Use Output Tab stuff"
