C API: Get the error associated with a RUBY_EVENT_RAISE event

ruby-talk

Hi,

I'm using rb_add_event_hook() with the RUBY_EVENT_RAISE flag, and I'm
struggling to find a function to tell me what error actually happened.
I know where it happened with rb_backtrace() which is great, but I still
need the name of the error.

Maybe I'm looking in the wrong place, but the documentation for the C API is
pretty much non-existent. Sure, we have doxygen generated lists of files and
functions but that's next to worthless without a description of what each
function does. The README only seems to cover the most common tasks, and
brief at that.

Cheers
Ian.

The last exception raised is stored in ruby_errinfo.

I agree; we should have better C documentation. What we do have:
  - README.EXT
  - The pickaxe book
  - the ruby hacking guide - http://rhg.rubyforge.org/
  - the ruby source code (I use this a lot)
  - ruby embedded into c++
  - numerous articles on the web

Perhaps someone should start a project to document the API.
