Hi Folks, 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 FileChannel.transferTo? 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. Cheers, Michael
