    Exclamation synchronous i/o URGENT HELP PLZZZ

    Right now I have a process writing a file and having another .exe come in and read that file and save the data to a buffer.
    I was just told the i/o process needs to be synchronous, so how exactly do I access a file that is being written to? THIS IS REALLY URGENT if anyone can help me. I can't find any good examples of "select system call" and have no idea how to use it.

    How To Ask Questions The Smart Way

    It's also a fairly unanswerable question without you telling us which OS/Compiler you're using.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    Had you Google'd, you would have come across this primer on select().
