[wmii] IXPClient.errstr vs error numbers

-----BEGIN PGP SIGNED MESSAGE-----

I understand, that whenever there occurs an error accessing files via
libixp, a string describing that error is written to IXPClient.errstr.
I wonder if there is something like an error code, a simple number for
each type of error. I mean, having a string describing an error is nice,
 but if i want to make decisions on what error occured, error numbers
would come in handy.
