c - does fork() have limit to how much it can create new process?

Question

I'm working on the 1 server-multiple client code to transfer file using socket, I'm using fork() to create new process for each client that connects to server. my question: is there any limit for fork() function to how much new process it can create?

Answer 1

There is not a specific limit if not the memory you have available. Since when you do a fork you're creating a new address space (which is a copy of that of the father) you obviusly can't create any more processes if those resources start to run out (EANOMEM error). I also think, but not sure, there may be a default limit to the number you can spawn, set by the OS.
