Nope, not really. Blocking writes are not a good idea here.

Oh, it can work perfectly without allocating a pa_card. But it would
be good if it did. That would clients to figure out which sink belongs
to which source.

No, I was referring to the MAX_PATH issue: MAX_PATH is not defined
everywhere since some OS have no limit on the filename length. So
relying on MAX_PATH is unportable as is passing NULL as second

I have now merged your patch. I had to change a few things to make it
apply cleanly. Since I have no access to Solaris I am unable to test
this though, so please check if things still work for you.

I also worked around the realpath() issue mostly. It should work fine
on Solaris now, as well.

Thanks again for your contributions.
