API ^

There exists an internal API

new

This accepts the following parameters by applying them through Getopt::Long. This is actually just a front for the script perl-stacktrace's command line handling.

  App::Stacktrace->new(
      $pid,       # The process to attach to
      'm',        # Dump the generated script
      'v',        # Verbose
      'exec',     # exec() into gdb
      '--noexec', # system() into gdb
  );

run

Runs the app program as configured by the ->new(...) method.

    $obj = App::Stacktrace->new( ... );
    $obj->run;
