vxworks standard I/O driver to be porting over RTEMS

Hi,

I wrote a simple discrete I/O driver in vxworks OS. This driver has no
interrupt, no semaphores or DMA (very simple driver). I need to port this
driver into the RTEMS 4.10 platform and I have run into registration issue.
My driver over vxworks support create/open/close/write/read/ioctl standard
API. The vxworks use the following to map my function to the I/O system
call:

iosDrvInstall(      (FUNCPTR)NULL,
                    (FUNCPTR)NULL,
                    (FUNCPTR)s441Open,
                    (FUNCPTR)s441Close,
                    (FUNCPTR)s441Read,      
                    (FUNCPTR)s441Write,    
                    (FUNCPTR)s441ioctl
               );
How should I register my driver under RTEMS system? 
Any template/example would be very very useful.

Thanks in advance,
Hagai
