    fork() question

    hi, does the child process have access to the parents declared variable?

    Child gets a copy of most things from the parent. If you need to access the actual instance within the parent process, you'll have to use some form of IPC - like shared mem, pipes, ect.. to "communicate" with the parent.

    So, what codeplug is saying is that you get a COPY of all the variables in the original process, but it's not the same variable as in the original process, so changing it won't actually change the original process's content in that variable.

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.
