DESCRIPTION
Header "DESCRIPTION" \fBERR_set_mark() sets a mark on the current topmost error record if there
is one.
\fBERR_pop_to_mark() 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.
\fBERR_clear_last_mark() removes the last mark added if there is one.
"RETURN VALUES"
Header "RETURN VALUES" \fBERR_set_mark() returns 0 if the error stack is empty, otherwise 1.
\fBERR_clear_last_mark() and ERR_pop_to_mark() return 0 if there was no mark in the error stack, which implies that the stack became empty, otherwise 1.
