+<p>Attempts to generate a stack trace at current code position in
+<em class="parameter"><code>prog_name</code></em>
+. <em class="parameter"><code>prog_name</code></em>
+ is mostly a helper and can be set to NULL.
+Nevertheless if set, it has to be the current program name (argv[0]).
+This function is not meant to generate stack trace for third-party
+programs, and will attach the current process id only.
+Internally, this function uses <code class="literal">gdb</code> or <code class="literal">lldb</code> if they are available,
+or the <code class="function">stacktrace()</code> API on platforms where it is available. It always
+fails on Win32.</p>
+<p>The stack trace, once generated, will either be printed to <em class="parameter"><code>stream</code></em>
+ or
+returned as a newly allocated string in <em class="parameter"><code>trace</code></em>
+, if not <span class="type">NULL</span>.</p>
+<p>In some error cases (e.g. segmentation fault), trying to allocate
+more memory will trigger more segmentation faults and therefore loop
+our error handling (which is just wrong). Therefore printing to a
+file description is an implementation without any memory allocation.</p>
