Hi,
Is there any mechanism for passing an open file descriptor from one process to another in SFU?
sendmsg and recvmsg do not appear to be implemented.

You' re right that sendmsg and recvmsg aren' t implemented.
There' s a wrapper to make these functions available, but they don' t do the kernel work for passing file descriptors.
I don' t know if there are plans to implement this in the future.
I don' t know you' re program(s), but the fork/exec method is one way of handles getting passed.

Thanks for the reply.
The fork/exec wouldn' t be very easy in this instance, the processes are already running when the transfer needs to take place.
Any ideas how I would find out whether there are any plans to implement this mechanism in Interix?

I can ask the dev group...
and then see what comes back.
The fact a real customer (you) has asked for the functionality gives it a better chance of happening.
