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

[Markus Kemp]

Hi all,

Well, basically the title says it all. I can't use os.access() because
it tests whether the REAL UID can read/write/exec the file. Surely
there has to be a function that does what I need, but I can't seem to
find it. Any input welcome.

Regards,

Markus
