|

|
|
|
||
|
|
#include <openssl/err.h>
|
||
|
|
|
||
|
|
int ERR_set_mark(void);
|

=head1 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.
|
||
|
|
|
||
|
|
ERR_clear_last_mark() removes the last mark added if there is one.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
ERR_set_mark() returns 0 if the error stack is empty, otherwise 1.
|
||
|
|
|
||
|
|
ERR_clear_last_mark() and ERR_pop_to_mark() return 0 if there was no mark in the
|
||
|
|
error stack, which implies that the stack became empty, otherwise 1.
