# Builtins.exceptionBacktrace(3kaya)

Print the backtrace of an Exception.

## NAME

Builtins::exceptionBacktrace - Print the backtrace of an Exception.

## SYNOPSIS

**Void exceptionBacktrace(** *Exception e* **)**

## ARGUMENTS

**e** The caught **Exception**

## DESCRIPTION

This is used to deal with uncaught exceptions in programs and prints the backtrace on standard output. It is generally not appropriate for use within a program except for debugging purposes, and should never be called within a CGI program or webapp.

If the program is compiled with the **-nortchecks**  compiler option then the backtrace will be of limited use. Similarly, the standard library must be compiled with the **--enable-debug**  configure option to get useful backtraces there.
