I have a subroutine which is interact with external file. How to make I this subroutine to synchronize? I am using in the following.

Example: $isAllowed = checkAndAllowed($pdt);

This checkAndAllowed($pdt) subroutine will rewrite the content of external file

If anyone knows, please share it here

Thanks in Advance, Kavitha
