NAME

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

DESCRIPTION

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

CONSTRUCTOR

new
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' );

METHODS

send
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.
get_reader
Returns the file handle from which to read GDB responses.
get_expect_obj
Returns the "Expect" object created in the constructor. Dies if '-create-expect' was not passed to "new".
interrupt
Send SIGINT to the GDB session, interrupting the inferior process (if any).
