Need function to test if EFFECTIVE UID has read-access to a file.

[Markus Kemp]

Oh, and another reason why I can't use the method suggested by you is
that I'm dealing with directories, not files. Then again .... I guess
I could do something like:


try:
    os.listdir( strPathname )
except:
    print "No read access to pathname", strPathname, "!"


Problem is, I don't wanna catch __everything__. Does anyone know what
kind of exception is.listdir() throws if it fails to read a directory?
