Question About Forking:
Including the initial parent process, how many processes are created by the program shown below? Show through a diagram the tree of process created giving process labels as P1, P2, P3, …
int main()
{
/* fork a child process */
fork();
/* Another fork */
fork();
int i;
for (i=0; i <5; i++)
fork();
/* fork another child process */
return 0; }
( I'd take a complete answer, but I'm mainly confused as to whether the initial 2 forks count in the "For" part of the process. Does int i start at i=0 or i=2? Would it go through a total of 4 forks or 6?)
Explanation / Answer
Yeah, initial 2 forks don't count in the for loop. They are separated from the forks created by the for loop. So, there are total 7 forks created. 2 by individual calls and 5 forks from for loop.
Hope it helps, feel free to comment in case of any query.
