144 ERR_set_mark, ERR_pop_to_mark \- set marks and pop errors until mark
148 .IX Header "SYNOPSIS"
150 \& #include <openssl/err.h>
152 \& int ERR_set_mark(void);
154 \& int ERR_pop_to_mark(void);
157 .IX Header "DESCRIPTION"
158 \&\fIERR_set_mark()\fR sets a mark on the current topmost error record if there
161 \&\fIERR_pop_to_mark()\fR will pop the top of the error stack until a mark is found.
162 The mark is then removed. If there is no mark, the whole stack is removed.
164 .IX Header "RETURN VALUES"
165 \&\fIERR_set_mark()\fR returns 0 if the error stack is empty, otherwise 1.
167 \&\fIERR_pop_to_mark()\fR returns 0 if there was no mark in the error stack, which
168 implies that the stack became empty, otherwise 1.
170 .IX Header "SEE ALSO"
171 \&\fIopenssl_err\fR\|(3)
174 \&\fIERR_set_mark()\fR and \fIERR_pop_to_mark()\fR were added in OpenSSL 0.9.8.
