<I>val location </I>
:
<B>t -&gt; Printexc.location option</B>
<P>
<P>
<B>location slot</B>
returns the location information of the slot,
if available, and
<B>None</B>
otherwise.
<P>
Some possible reasons for failing to return a location are as follow:
<P>
-the slot corresponds to a compiler-inserted raise
<P>
-the slot corresponds to a part of the program that has not been
compiled with debug information (
<B>-g</B>
)

<I>val format </I>
:
<B>int -&gt; t -&gt; string option</B>
<P>
<P>
<B>format pos slot</B>
returns the string representation of
<B>slot</B>
as
<B>raw_backtrace_to_string</B>
would format it, assuming it is the
<B>pos</B>
-th element of the backtrace: the
<B>0</B>
-th element is
pretty-printed differently than the others.
<P>
Whole-backtrace printing functions also skip some uninformative
slots; in that case,
<B>format pos slot</B>
returns
<B>None</B>
.
