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.
