| |
Hello, This is the simple program that I tried on a - 2.4.20-30.9smp #1 SMP Wed Feb 4 20:36:46 EST 2004 i686 i686 i386 GNU/Linux (kernel) machine.
The ps command doesn't show me the process. /proc/ shows that these process are present in the system. When I uncomment the call getpid(). Then it shows me the process. I am not able to understand this behavior and I hope this is the right place to post this question/bug.

#include <unistd.h> #include <stdio.h> #include <sys/types.h> #include <sys/wait.h>
int main() { int i = 3; pid_t pid, pidarr[3];
for(i = 0; i < 3;i ++) { if ( (pid = fork()) == 0) { while(1){ /* getpid(); */ } } pidarr[i] = pid; } for(i = 0; i < 3;i ++) { waitpid(pidarr[i], NULL, 0); } return 0; }
