Should I use a CriticalSection on WriteFile calls?

I have an application in Windows CE that creates multiple threads that can at any time make a call to a log function that uses a WriteFile call. Should I use a CriticalSection around the WriteFile call and/or all the internals of the api that uses the WriteFile function or does WriteFile handle the proper sequence when multiple threads call it?

Thanks

These are all good answers. I never know how to give out points. jkr was first with an answer but Frosty555 and JimDeveridge both gave additional useable commnets. What do you guys suggest?
Thanks
You can split the points as you see fit. You don't have to award all of the points to one person.
