ERR_set_mark(3)                     OpenSSL                    ERR_set_mark(3)

NAME
       ERR_set_mark, ERR_pop_to_mark - set marks and pop errors until mark
SYNOPSIS
        #include <openssl/err.h>
        int ERR_set_mark(void);
        int ERR_pop_to_mark(void);
DESCRIPTION
       ERR_set_mark() 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.
RETURN VALUES
       ERR_set_mark() returns 0 if the error stack is empty, otherwise 1.
       ERR_pop_to_mark() returns 0 if there was no mark in the error stack,
       which implies that the stack became empty, otherwise 1.
