Re: debug.traceback as an error handler for coroutines

[Matt Campbell <mattc@...>]

Please disregard my previous question.  On examining the C source for 
debug.traceback (db_errorfb in ldblib.c), I found that debug.traceback 
can take a thread as its first argument and provide a traceback of the 
call stack for that thread, which isn't unwound on error according to 
the manual's description of lua_resume.  So this can be used with 
coroutine.resume as follows:

local succeeded, result = coroutine.resume(c)
if not succeeded then
 print(debug.traceback(c, result))
end

Problem solved.
