<para>
The <function>maxdb_error</function> function is identical to the corresponding
<function>maxdb_errno</function> function in every way, except instead of returning
an integer error code the <function>maxdb_error</function> function will return
a string representation of the last error to occur for the database connection
represented by the <parameter>link</parameter> parameter. If no error has occured,
this function will return an empty string.
