<b>Description: DBcursor->close</b>
|
|
<p>The DBcursor->close method discards the cursor.</p>
|
|
<p>It is possible for the DBcursor->close method to return
|
|
<a href="../ref/program/errorret.html#DB_LOCK_DEADLOCK">DB_LOCK_DEADLOCK</a>, signaling that any enclosing transaction should
|
|
be aborted. If the application is already intending to abort the
|
|
transaction, this error should be ignored, and the application should
|
|
proceed.</p>
|
|
<p>After DBcursor->close has been called, regardless of its return, the
|
|
cursor handle may not be used again.</p>
|
|
<p>The DBcursor->close method
|
|
returns a non-zero error value on failure
|
|
and 0 on success.
|
|
</p>
|
|
<br><b>Errors</b>
|
|
<p>The DBcursor->close method
|
|
may fail and return one of the following non-zero errors:</p>
|
|
<br>
|
|
<b>DB_LOCK_DEADLOCK</b><ul compact><li>A transactional database environment operation was selected to resolve
|
|
a deadlock.</ul>
|
|
<b>DB_LOCK_NOTGRANTED</b><ul compact><li>A Berkeley DB Concurrent Data Store database environment configured for lock timeouts was unable
|
|
to grant a lock in the allowed time.</ul>
|
|
<br>
|
|
<br>
|
|
<b>EINVAL</b><ul compact><li>If the cursor is already closed; or if an
|
|
invalid flag value or parameter was specified.</ul>
