Hey Thanks. Will do that. Just a question in general. Is it possible that we have opened one file in r+ mode ( file1.txt ). We have 2 threads, thread1 will continuously only read the file in a loop. Thread2 will only update the data in the file. Now thread2 has called other script ( written in say Perl/Powershell ) and those scripts are inturn updating ( only writing ) into that file by their own file i/o mechanism. Is it possible by any chance? One file being shared between different processes one is updating and other is reading ..? Will this work in practical and what can be the complications ?
