win95 driver question

I am sorry for asking 95 driver question to nt list. If anyone can help
me please.
I have an x.drv and a y.vxd as my driver files. I have to call a
function that is present in x.drv from y.vxd. Can I do so? Is it
possible ? Or can I send a message to x.drv from y.vxd that x.drv can
handle this in its DriverProc function ?

Thanks in advance
