Stack Traces
When an exception is caught, we can find the latest stack trace
by calling erlang:get_stacktrace()
. Here’s an
example:
try_test.erl | |
| demo3() -> |
| try generate_exception(5) |
| catch |
| error:X -> |
| {X, erlang:get_stacktrace()} |
| end. |
| 1> try_test:demo3(). |
| {a,[{try_test,generate_exception,1,[{file,"try_test.erl"},{line,9}]}, |
| {try_test,demo3,0,[{file,"try_test.erl"},{line,33}]}, |
| {erl_eval,do_apply,6,[{file,"erl_eval.erl"},{line,576}]}, |
| {shell,exprs,7,[{file,"shell.erl"},{line,668}]}, |
| {shell,eval_exprs,7,[{file,"shell.erl"},{line,623}]}, |
| {shell,eval_loop,3,[{file,"shell.erl"},{line,608}]}]} |
The previous trace shows what happened when we tried to evaluate
try_test:demo3()
. It shows that our program crashed in the function ...
