Possibly.  I was just copying the way it was handled in some other LTP 
tests, i.e.,

   testcases/kernel/syscalls/link/link04.c
   testcases/kernel/syscalls/lstat/lstat02.c

but I'm open to suggestions.

Me either.  I'm just using trial and error at the moment (see what 
works).  Many (most) syscalls tests have code to skip unsupported 
functions based on UCLINUX=1, but a few seem to be missing that test.

I'm working my way through the list, so suggestions are welcome.


Thank you,
