Re: How to synchronize the one subroutine

I'm not sure exactly what you are looking for. What is it that you want to synchronize your subroutine with?

Maybe you want to flush the buffers of the external file? Look at $| in perlvar, but closing the file would do that.

Maybe you have other scripts you need to synchronise with. Look at flock (UNIX/Linux) or Win32::Mutex (Windows), or maybe other IPC mechanisms.

Thanks for your information One of the subroutine of our tool is exposed with external file like writing, rewriting, remove entry. Currently, when multiple user tried to use this tool at the same time, external file content has changed irrelevently. My requirement, external file should be edit by only one user at a time	[reply]
