<CODE>ERR_set_mark()</CODE> sets a mark on the current topmost error record
if there is one.

</P>
<P>
<CODE>ERR_pop_to_mark()</CODE> will pop the top of the error stack until a
mark is found. The mark is then removed. If there is no mark, the whole
stack is removed.

<H1><A NAME="RETURN_VALUES">RETURN VALUES</A></H1>
<P>
<CODE>ERR_set_mark()</CODE> returns 0 if the error stack is empty,
otherwise 1.

</P>
<P>
<CODE>ERR_pop_to_mark()</CODE> returns 0 if there was no mark in the error
stack, which implies that the stack became empty, otherwise 1.
