Hello All,
I´m using mod_perl2 and Apache2 over Fedora Core 1.
I have a handler that need to call an external program to complete the request.
This program put its output to a file, and then I read this output from the handler (after system function) to complete the request.
My problem is (I assume) when I call system, it returns inmediatly and of course when I try to read the file output, it does not exist; becase it was created later.
How can I force to wait for a system function terminate the execution of an external program.
Sounds like a generic perl question, not really specific to mod_perl. Take a look at IPC::Run or IPC::Run3. Hopefully you will find a better place to discuss this, like perlmonks.org. Thanks.
