I thought of using fork. but in case I have 100 files, I must have to fork 100 times, where one process reads one file at a time and pumping data to a single(same) client. When the second client connects it would be a mass fork of again 100 processes.

Maybe I'm the only one who has trouble understanding this paragraph as others have answered without quesioning it, but it's not at all clear to me why you feel you need to "fork 100 times" in order for "one process reads one file at a time and pumping data to a single(same) client"?

Essentially, it is not clear from your post what you trying to do, but reading between the lines, it may be something like:

  1. Open a listening socket:
  2. When a client connects, select one of 100 hundred files and send it to that client; disconnect.
  3. Repeat.

If that's an accurate picture of the requirement, then it can easily be satisfied with either fork or threads, and without the 'mass spawnings' that you seem to think are involved.

If that is an inaccurate description of then you need to clarify the actual requirements before you will get useful answers.
