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 --- . o o . o . o .. o .. o .. o oo . o . o o o _n_n_n____i_i _++++++_ _______ ________ _+++++++++++_ *>(____________I I______I I_____I I______I I___________I __^__ /ooOOOO OOOOoo oo ooo oo oo oo oo ooo ooo __^__ ( ___ )--------------------------------------------------------( ___ ) | / | Paal Halvorsen UniK - Center for technology at Kjeller | \ | | / | University of Oslo | \ | | / | Phone: +47 64844731 PB. 70 | \ | | / | Phone: +47 64844700 (switchboard) N - 2027 KJELLER | \ | |_/_| Fax: +47 63818146 Norway |__| (_____)-- E-mail: paalh@unik.no -- http://www.unik.no/~paalh --(_____)
