<p>ERR_set_mark, ERR_pop_to_mark - set marks and pop errors until mark</p>
<h1 id="SYNOPSIS">SYNOPSIS</h1>
<pre><code> #include <openssl/err.h>
int ERR_set_mark(void);
int ERR_pop_to_mark(void);</code></pre>
<h1 id="DESCRIPTION">DESCRIPTION</h1>
<p>ERR_set_mark() sets a mark on the current topmost error record if there is one.</p>
<p>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.</p>
<h1 id="RETURN-VALUES">RETURN VALUES</h1>
<p>ERR_set_mark() returns 0 if the error stack is empty, otherwise 1.</p>
<p>ERR_pop_to_mark() returns 0 if there was no mark in the error stack, which implies that the stack became empty, otherwise 1.</p>
