You can try it and see what happens. In what context are trying to find out whether it works? In general it should be supported on Linux kernels with version >= 2.6.0 and using a sufficiently recent glibc--I think 2.4 should suffice. It should also work on sufficiently recent Solaris systems. I don't know about other systems. Ian
