NAME

ExtUtils::ExCxx - Let perl use ANSI C++ exceptions.

SYNOPSIS

use ExtUtils::ExCxx;

DESCRIPTION

Replaces perl's default tryblock method with a C++ try/throw style method. This should be completely transparent (except to extensions that secretly invoke low-level exception handling routines).

PATCH

At the moment, this extension requires patches to the perl source code. Hopefully, these changes will make it into the next developer release. Either apply stage0[1-3] or the whole.patch to 5.004_56.

'make test' should be 100%!

(FYI: You don't need to built this extension to test the patch.)

ALSO

call_list should probably be optimized to call tryblock only once instead of doing it for each BEGIN or END block. However, the control flow is messy enough that I didn't attempt it.

dJMPENV is setjmp-centric. This might be construed as a bug.

FUNCTIONS AFFECTED

• JMPENV_PUSH

  perl_call_sv
  perl_eval_sv
  docatch
  perl_parse
  perl_run
  call_list

• JMPENV_JUMP

  die
  croak
  docatch
  pp_goto
  calllist
  my_exit_jump

BUGS

sigsetjmp saves more state than a C++ try block. sigprocmask & priocntl stuff should be addressed.
