Ahum ... i will have to design such a prototype.

This gives me new questions.
Language:
Why no "in" or "out" before parameter "device" ?
How to say "in and out" ?
Can you give me an URL where the language is documented ?
Wiring:
I still need to find out how to get the Scsi_Device parameter of
gnumach/linux/src/drivers/scsi/scsi_ioctl.c:
int scsi_ioctl_send_command(Scsi_Device *dev, void *buffer)
from
device_t
Naming conventions:
How to name the function ? device_transact_scsi() ?

I found the struct definition in gnumach/device/device_emul.h .
There i read
/* Each emulation layer provides these operations. */
Does that mean, that all instances of struct device_emulation_ops
have to be augmented by a function pointer ?
I see 7 of them by
grep -r 'struct device_emulation_ops .* =' gnumach | less
(ignoring gnumach/device/ds_routines.c:emulation_list)
Have a nice day :)
