General process questions

[Guenther Sohler]

I have some simple c "enviroment questions"

* How can I find out, if a process number 4563 is still alive ?

* How Can I find the User id, a process runs on ?

* How can I find out the user name related to the user id ?


Thank you for your tips

This is not a C question, since processes and their ids are specific to
an implementation. Check the system calls available to you, none of
which will be standard C functions. If you have a problem finding such
information, ask in a newsgroup for your implementation or platform, but
only after checking that NG's FAQ and previously posted questions.

See above.

* How can I find out the user name related to the user id ?

See above.
