I have written a package in Tcl to log data to a file. This package
creates one file per day and the users can use the package to log data
to this file. Many users will eventually start using the pacakage and
might write to the file at the same time. Is there a way in Tcl to do
file locking so that only one particular user can write to the file at
a time.
