How to synchronize FileAccess between different Threads

Hello

I have java and c# background but not much experience with structual
programming.

In a tcl-programm i have different threads who can read and write
from/to one file. As i saw, theres no synchronzized-Keyword in tcl to
make some codeblocks synchronized.

Do i have to implement the synchronisation myself or are there any
extensions to tcl which provide what i am looking for?

I think that only write-Access have to be synchronized, is that right?

thx for help
