        and <a href="http://www.dirac.org/linux/gdb/02a-Memory_Layout_And_The_Stack.php">Memory Layout and the Stack</a>

        <p>To use gdb you need to compile program with -g flag. To
        debug a program;</p>

        <pre>
        gdb program
        </pre>

        <p>If the program needs arguments you can set it;</p>

        <pre>
        (gdb)set args -parameter1 -parameter2
        </pre>

        <p>To start the program you can type run, this way gdb
        will try to run the program until the end. If program
        crash, gdb will stop it for debuging.</p>

        <pre>
        (gdb) run
        </pre>

        <pre>
        n - execute next line
        s - step in next line
        b - backtrace
        info locals
        print
        x
        </pre>

        <h2>SysCalls</h2>

        <pre>catch syscall open</pre>

        <h2>Threads</h2>

        <p>When new thread is created you receive
        a notification. To get information about
        threads;</p>

        <pre>
        info threads
        </pre>

        <p>To select thread;</p>

        <pre>
        thread 1
        </pre>
