<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>
|
||
|
|
|
||
|
|
<p>ERR_clear_last_mark() removes the last mark added if there is one.</p>
|
||
|
|
|
||
|
|
<p>ERR_count_to_mark() returns the number of entries on the error stack above the most recently marked entry, not including that entry. If there is no mark in the error stack, the number of entries in the error stack is returned.</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_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.</p>
|
||
|
|
|
||
|
|
<p>ERR_count_to_mark() returns the number of error stack entries found above the most recent mark, if any, or the total number of error stack entries.</p>
