<simpara>
<function>dbx_error</function> returns a string containing the error
message from the last function call of the abstracted module (e.g.
mysql module). If there are multiple connections in the same module,
just the last error is given. If there are connections on different
modules, the latest error is returned for the module specified by the
<parameter>link_identifier</parameter> parameter.
