create a process tree in C

Question

How would I approach creating a process hierarchy that would look like a balanced ternary tree of depth N? ... meaning each process has 3 children so there would be (3^N-1)/2 pr

Answer 1

This bit does not look right to me:

for(x=0; x<3; x++) {
   fork();
   createTernaryTree(n-1);
}

The problem is that both the parent and the child continue looping and do the recursion.

Based on the return from fork (0 in the child, > 0 in the parent, -1 on error), you should decide whether to loop or recurse.
