<h1>Description</h1>
<p>The <i>db</i> <b>cursor</b> command creates a database cursor. The returned
cursor handle is bound to a Tcl command of the form <b>dbN.cX</b>, where
X is an integer starting at 0 (e.g., db0.c0 and db0.c1). It is through
this Tcl command that the script accesses the cursor methods.
<p>The options are as follows:
<p><dl compact>
<p><dt>-txn txnid<dd>If the file is being accessed under transaction protection, the
<b>txnid</b> parameter is a transaction handle returned from <i>env</i> <b>txn</b>.
</dl>
<p>In the case of error, a Tcl error is thrown.
