using the sendfile system call on Darwin

I would like to update jdk/src/solaris/native/sun/nio/ch/FileChannelImpl.c
so that the Java_sun_nio_ch_FileChannelImpl_transferTo0 function calls the
sendfile system call on Darwin. I have a few questions:
1. Is there a cpp #define for Darwin? If not, how do I tell cpp whether
the system is Darwin or not?
2. Are there tests that exercise
Java_sun_nio_ch_FileChannelImpl_transferTo0 or the java method
3. Why doesn't the existing BSD code just return IOS_UNSUPPORTED? For
instance, look at lines 223 and 224. If there's no sendfile function on
Solaris, the function just returns IOS_UNSUPPORTED. The caller handles
that return value gracefully. The existing BSD code looks needlessly
complex to me.
