    Question how to get output of a process?

    First, I ask the user name and password to start a telnet/ssh session. Then I want to get the output of the telnet/ssh session to deterrmine the next action.

    Use popen? The telnet/ssh session is still running, I afriad the buffer in fgets would overflow.

    sorry about posting, but what..

    popen() and pclose() means?
    Hmm did you change the 'f' to 'p', or this is just another function?

    Thanks

    ...

    Pretty ignorant and narrow-minded.
    I just asked, I really didn't know that popen() and pclose() exists, now I do know, thanks.

    VBer: Man pages. Use them and love them instead of asking silly questions. And don't give me any "I'm on windows" junk. www.freebsd.org has them with a pretty web front-end.

    Now tell me - why on Earth should he learn to "use and love" documentation for a system that he doesn't program for? I should think a more approriate place to point him would be http://msdn.microsoft.com - the man pages of windows

    Because he may be asking about a non windows function. Although, I do agree msdn is a wonderful place for windows developers.
