Subjectsendfile
Hi!

I'm a Norwegian PhD student looking at zero-copy data paths through the OS
kernel and found sendfile to be interesting. Do this system call remove
all in-memory copy operations, i.e., sharing data buffers between file
system and com. system? (i'm sending data from disk to the network)

Is there any documentation about sendfile?

PS! I'm not a member of the mailing list so please cc the answers to my
mailing address

Thank you in advance,
-ph
