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).
