    Exclamation Socket function "Select" crashes...????

    Hi,

    In one of my application the socket function call "Select" crashes. It doesn't happen everytime. If anyone knows the reason for the "Select" function to crash.
    I checked for the proper values in the FD_Set structure for writefds and its proper i.e. {1, socket_handle}. I am not able to figure out the reason for the crash to happen with "Select" function.

    Any help !

    Thanks!

    Faulty coding on your part.

    The first thing you should do is to get a sample application not written by you that uses the Socket() function, and see if it works with no errors. If it works, then again, it is faulty coding in your application that only you can solve since we don't have your program.

    Thanks Paul ! By faulty coding you mean to say that there may be the chances of invalid socket handle, invalid FD_Set struct right ??? I cannot share my code but thanks for your reply i'll check once more on the parameters being sent to the "Select" function.

    Faulty coding could be anything. You're programming in C++, and any mistakes anywhere can cause problems at any place or time in the program. That's why no one can give you an answer as to what the problem is.

    That's also why it is better you get a small working application not written by yourself, and see if it works with your parameters and data. Just grab something that is 10 or 20 lines long off the Internet, compile it, and run it with your parameters. Then you know if what you're doing really works correctly.
