Exclamation How are Standard Streams Defined?


I would like to know how a Linux System defines Standard Streams.

I would like to use this knowledge to allow multiple users to use the same computer, but through different sources of input/output. That is, the computer may have mutliple keyboards, mice, and screens attached for all I/O.

I am a bit familiar with file descriptors and how they can be redirected (ex: the output of a command into a file), but I would like each user to log into the system through one of the various input devices, and once logged in, communicate with the computer using the corresponding set of I/O devices I have in place

So to keep it simple, if I have 2 mice, keyboards, and monitors attached to a computer, I want User A t use the first set of I/O devices and User B to use the second set

Thank you very much.

Have you looked at:

It would seem to fit your needs a bit more than trying to start from scratch.

I appreciate the link, Ive come across it before.

I'm more interested in knowing how it works then to implement my design. I provided my list of goals in creating thin clients to give you an idea of what information I am looking for.

the question I am trying to asnwer is: How are Standard Streams (stdin/out/err) defined? How can they be assigned?

In this case, I am more interested in how the Linux System works then trying to apply this to my goals.

Besides... I like to know how things work- so on the programming/administration scale I only try my hardest to get lower level. Of course this is not necessarily practical, but it's not a minstream computer- I just do this as a hobby
