141 ERR_set_mark, ERR_pop_to_mark \- set marks and pop errors until mark
143 .IX Header "SYNOPSIS"
145 \& #include <openssl/err.h>
147 \& int ERR_set_mark(void);
149 \& int ERR_pop_to_mark(void);
152 .IX Header "DESCRIPTION"
153 \&\fIERR_set_mark()\fR sets a mark on the current topmost error record if there
156 \&\fIERR_pop_to_mark()\fR will pop the top of the error stack until a mark is found.
157 The mark is then removed. If there is no mark, the whole stack is removed.
159 .IX Header "RETURN VALUES"
160 \&\fIERR_set_mark()\fR returns 0 if the error stack is empty, otherwise 1.
162 \&\fIERR_pop_to_mark()\fR returns 0 if there was no mark in the error stack, which
163 implies that the stack became empty, otherwise 1.
165 .IX Header "SEE ALSO"
169 \&\fIERR_set_mark()\fR and \fIERR_pop_to_mark()\fR were added in OpenSSL 0.9.8.
