Devel::GDB::LowLevel - Low-level interface for communicating with GDB


This module is used internally by Devel::GDB. It handles the low-level I/O of communicating with the GDB process.


Spawns a GDB process. Because this class only facilitates communication with GDB (not with the inferior process being debugged), you have to decide what to do with the "STDIN", "STDOUT", and "STDERR" of that process. There are a few options available:
  • If STDIN is a tty, we can have the inferior process communicate directly with the controlling tty (emulating the default behavior of gdb):

        $gdb = new Devel::GDB::LowLevel( '-execfile' => $path_to_gdb,
                                         '-params'   => $extra_gdb_params );
  • Or, we can create an "Expect" object to communicate with the inferior process:

        $gdb = new Devel::GDB::LowLevel( '-create-expect' => 1 );
        $expect = $gdb->get_expect_obj();
  • Or, we can create our own tty and use that:

        $gdb = new Devel::GDB::LowLevel( '-use-tty' => '/dev/pts/123' );


Sends a raw line of text to GDB. This should not contain any newlines (they will be stripped). This method only sends a request, and does not wait for a response.
Returns the file handle from which to read GDB responses.
Returns the "Expect" object created in the constructor. Dies if '-create-expect' was not passed to "new".
Send SIGINT to the GDB session, interrupting the inferior process (if any).
