(i.e. read, write, - open, close, etc.?) - <youpi> it's the normal way of operation - <youpi> glibc's read() doesn't do a system call, it always does an RPC to - the underlying translator - <youpi> be it ext2fs for /, or your foobarfs for your node - <sea4ever> Ok that makes sense. How does one program know which translator - it should refer to though? - <sea4ever> the read() call magically knows which process to invoke? - <youpi> the / translator is always known - <youpi> and then you ask /'s translator about /home, then /home/you, then - /home/you/foobar - <youpi> it tells you which other translator tyou have to contact - <youpi> that's on open - <sea4ever> It's a tree! Ok. - <youpi> the notion of fd is then simply knowing the translator - <sea4ever> Right. 'file descriptor' is now 'translator address descriptor' - maybe. - <youpi> it's glibc which knows about FDs, nothing else knows - <youpi> yes - <youpi> actually an RPC port, simply - <sea4ever> I want to try out the new RPC mechanism that mach implements - <youpi> err, which "new" RPC ? - <youpi> mach's RPCs are very old actually :) |
