131 .IX Title "ERR_set_mark 3"
132 .TH ERR_set_mark 3 "2009-07-23" "0.9.8k" "OpenSSL"
134 ERR_set_mark, ERR_pop_to_mark \- set marks and pop errors until mark
136 .IX Header "SYNOPSIS"
138 \& #include <openssl/err.h>
142 \& int ERR_set_mark(void);
146 \& int ERR_pop_to_mark(void);
149 .IX Header "DESCRIPTION"
150 \&\fIERR_set_mark()\fR sets a mark on the current topmost error record if there
153 \&\fIERR_pop_to_mark()\fR will pop the top of the error stack until a mark is found.
154 The mark is then removed. If there is no mark, the whole stack is removed.
156 .IX Header "RETURN VALUES"
157 \&\fIERR_set_mark()\fR returns 0 if the error stack is empty, otherwise 1.
159 \&\fIERR_pop_to_mark()\fR returns 0 if there was no mark in the error stack, which
160 implies that the stack became empty, otherwise 1.
162 .IX Header "SEE ALSO"
166 \&\fIERR_set_mark()\fR and \fIERR_pop_to_mark()\fR were added in OpenSSL 0.9.8.
