Is it worth picking up Unix skills?

I mean this as a serious question. I have a chance at accepting a job offer with a company requiring skills in Unix (although they seem fine with my admittance of having only Windows experience, expecting me to be able to pick up Unix with the job).

How can I determine whether a message type is sent or posted?

I'm aware that some messages types are sent directly to window procedures, while others are posted to a thread's message queue, but I haven't found any way to determine if a message will be sent or posted.
