Function system

[cybernetykpl]

Hellow,
When we use function system("ps -aux | wc -l"); to x =28.
As it does not use function system("ps -aux | wc -l"); it returns x = 38867.
Which is the correct count?
X is to be type long int.

#include <signal.h>
#include <unistd.h>
#include <cstdlib>
#include <stdio.h>

int main(void)
{
	long int x = 0;
	alarm(1);
	while (1)
	{

printf("X=: ");
		printf("%li\n", x);
		x++;
printf("ID process: ");
printf( "pid %d ppid %d\n ", getpid(), getppid());

system("ps -aux | wc -l"); 
}
	return 0;
}

Your question is not clear.


Nevertheless, why do you spawn several processes to count running processes? Use the OS API.
