RPC interface directional attribute parameters

Hi

Can anyone explain to me what the [out]
paramater attribute is for in an interface
function definition.
I have read that it passes the parameter value
back from the server to the client but i dont
understand why the client needs this paramater
passed back..for what purpose?..also i thought
functions can only have one return value not
mulitple return values.
Any help would be greatly appreciated.
cheers
jack
