Using the program in Figure 3.23, identify the values of pid at lines A, B, C, and D.
(Assume that the actual pids of the parent and child are 2600 and 2603, respectively.)
#include <sys/types.h>
#include <stdio.h>
#include <unistd.h>
int main()
{
pid-t pid, pid1;
/* fork a child process */
pid fork();
if (pid < 0) { /* error occurred */
fprintf(stderr, "Fork Failed");
return 1;
}
else if (pid == 0) { /* child process */
pid1= getpid();
printf("child: pid=%d",pid); /* A */
printf("child: pidi = %d",pid1); /* B */
}
else { /* parent process */
pidi
getpid ();
printf("parent: pid=%d",pid); /* C */
printf ("parent: pid1= %d",pid1); /* D */
wait (NULL);
}
return 0;
