Avoid multiple process writing to a file at the same time

kkavitha has asked for the wisdom of the Perl Monks concerning the following question:

I have a perl project, one of the module in this project is writing some data into a file(specific to host). While running this project more than once at the same time, data in the file gets collpased. Because, more than one process is writing to the file at the same time. How to lock the file handle of that file? How to unlock the file handle once writing/reading done?

Thanks N Advance, Kavitha

As well as ccn's excellent pointer, OP might also want to have a look at the code in : File Locking Writing to one file from multiple processes I have found the discussions there very useful! HTH Just a something something...	[reply] [d/l]
