There are various fringe markings that show up in c-mode in emacs (24.4.1). By inference I've figured out that the yellow >> is a warning of some sort, whereas the red >> is an error. But I'd like to be able to know explicitly what the c-mode syntax evaluator thinks is actually the reason why it's marked that line in the fringe. How do I find this out? I've tried clicking on the fringe. Is there some command I can run when placing my cursor on that line?

The standard/default `c-mode` is a major-mode that does nothing special to the fringes as far as I am aware. Do you have a minor-mode running that might account for special fringe markings, e.g., `flymake` or something like that? Do you also have a particular theme active that modifies the default colors of a minor-mode that creates fringe markings? `M-x describe-mode RET` – lawlist May 23 '16 at 04:49

I'm using prelude which enables a bunch of stuff. Hmm on closer look it appears that it uses cc-mode (http://cc-mode.sourceforge.net/) not c-mode, oh, and there it is, FlyC that's what's doing it. http://www.flycheck.org/en/latest/user/error-interaction.html Thanks! – zippy May 23 '16 at 12:52

Fringe marks for any line can be listed with (fringe-marks-at-pos). For more information on that function, see the manual.
