Hello yesterday I have one question it is here: Question

And now I have other problem, I have the code based on answer by some guy

And now I have a problem I need for all children to see the pids of other child, how can i do that?? I try using global variables, but maybe in wrong way.

Please help I need a fast answer

Solution

  • Create a file with the parent process and write pids of all children. Read this file from the children after some delay. You can write out, N, the number of children first and then N lines each line containing one pid.
