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.
