    is a socket writable

    How can i find out if a socket if writable?
    I am programming for windows.
    I would like the easiest solution(Dont need to be portable, i love windows )

    If you plan to reffer to the select() function, i have looked it up on MSDN , and
    1. I did not understand it
    2. It looks like a overkill for this little task

    You're implying a an active socket (connected) correct? In that case, select() is a good solution.

    How about something like:

    Code:
    if((socket != NULL) && (socket != SOCKET_ERROR) && (socket != INVALID_SOCKET))

    That wont work. The only way to tell (that I know of) whether you can write to a socket is to call select(). You can find an example at http://www.ecst.csuchico.edu/~beej/g...et_old/#select
