ERR_set_mark(3)                     OpenSSL                    ERR_set_mark(3)



NAME
       ERR_set_mark, ERR_pop_to_mark - set marks and pop errors until mark

LIBRARY
       libcrypto, -lcrypto

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.
