     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.
