\&\fIERR_set_mark()\fR sets a mark on the current topmost error record if there
is one.

\&\fIERR_pop_to_mark()\fR 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.
.SH "RETURN VALUES"

\&\fIERR_set_mark()\fR returns 0 if the error stack is empty, otherwise 1.
.PP
\&\fIERR_pop_to_mark()\fR returns 0 if there was no mark in the error stack, which
implies that the stack became empty, otherwise 1.
