File open check command

[nikhil079]

Hi,
I am new to Tcl language and there must be some command I am missing here.

Using tcl script, I want to check if a file is already open on a machine. Is it possible? (when I say 'Open', I mean, user either double click on a that file to read its contents or some other process to open the file.)

Thanks in advance..

Regards
Nikhil

I don't think such a command exists. All Tcl can tell you is if Tcl can or can't access a file. This would be by attempting to open it and catching the error (with 'catch'). You can also execute any OS command with "exec" but, again, I don't know what will tell you if a file is open.
