ERR_SET_MARK(3ossl) OpenSSL ERR_SET_MARK(3ossl)
NAME
ERR_set_mark, ERR_clear_last_mark, ERR_pop_to_mark, ERR_count_to_mark -
set mark, clear mark and pop errors until mark
SYNOPSIS
#include <openssl/err.h>
int ERR_set_mark(void);
int ERR_pop_to_mark(void);
int ERR_clear_last_mark(void);
int ERR_count_to_mark(void);
DESCRIPTION
ERR_set_mark(3) sets a mark on the current topmost error record if there
is one.
ERR_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.
ERR_clear_last_mark() removes the last mark added if there is one.
ERR_count_to_mark() returns the number of entries on the error stack
above the most recently marked entry, not including that entry. If
there is no mark in the error stack, the number of entries in the error
stack is returned.
RETURN VALUES
ERR_set_mark(3) returns 0 if the error stack is empty, otherwise 1.
ERR_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.
ERR_count_to_mark() returns the number of error stack entries found
above the most recent mark, if any, or the total number of error stack
entries.
