NAME

6       ERR_set_mark, ERR_clear_last_mark, ERR_pop_to_mark - set mark, clear
7       mark and pop errors until mark
8

SYNOPSIS

10        #include <openssl/err.h>
11
12        int ERR_set_mark(void);
13        int ERR_pop_to_mark(void);
14        int ERR_clear_last_mark(void);

DESCRIPTION

17       ERR_set_mark() sets a mark on the current topmost error record if there
18       is one.
19
20       ERR_pop_to_mark() will pop the top of the error stack until a mark is
21       found.  The mark is then removed.  If there is no mark, the whole stack
22       is removed.
23
24       ERR_clear_last_mark() removes the last mark added if there is one.
25

RETURN VALUES

27       ERR_set_mark() returns 0 if the error stack is empty, otherwise 1.
28
29       ERR_clear_last_mark() and ERR_pop_to_mark() return 0 if there was no
30       mark in the error stack, which implies that the stack became empty,
31       otherwise 1.
