Is the system() function non-blocking?
|
| Solution |
Here is a small program to test it and it appears that it is blocking:
#include <stdio.h>
#include <stdlib.h>
void main()
{
printf("start n");
system("sleep 5");
printf("end n");
}
Remember also, that in order to return the exit status of the command, it must wait to get the status. |
