\defgroup chapter_attach_gdb Starting A gdb Session From A Running Program
\ingroup book_attach_gdb

/*!
\page page_attach_gdb
\ingroup chapter_attach_gdb
A running program can initiate a gdb session by calling the function <code>attach_gdb()</code>.
For example,
\code
Debug(
if (counter == 31523 && ptr == (void*)0x40013fa0) // When to start debugging?
attach_gdb();
);
ptr->foobar++; // The debugging will start at this line.
\endcode
The function <code>attach_gdb()</code> opens an xterm (or whatever is configured in the rcfile)
and starts the gdb session inside it.
After exiting gdb the application will continue running.
In order for <code>attach_gdb()</code> to work, you will need to call
<code>\link chapter_rcfile read_rcfile() \endlink</code>
at the start of your application.
