<fcntl snipped>
I therefore do not consider it to be "dummy".
L4VFS is meant to be extended on a use-case basis, it has grown over the last 1 1/2 years as other projects utilized it. Maybe you have to extend it a little bit. We gladly accept patches (hint, hint).
;)... ok i've understood the hint. but the dummy i've talked about was the implementation of l4vfs_*_fcntl_component(...). that is the implementation of the dielibc...
This has *nothing* to do with the dietlibc!
bue when it calls the server side function it's not implemented.
Your are quite unprecise with your statements. Which fcntl do you mean? Are you talking about l4vfs/lib/server/fcntl.c? This is the weak implementation of the server lib. Every server which implements fcntl() functionality shall provide its own impl. overriding this weak dummy impl.
I think you now know were to start coding ...
my question was if in one of those projects someone implemented it
I dont know of any such thing.
