modify this program so that it used clone instead of fork.

the output should be

This is process(thread) 11501. x+y=1 > This is process(thread) 11502. x+y=7

//fork makes a second process, running the same executable

//pid_t used to be long, but now just int #include #include #include int main ( void ) { int x=0, y=0; pid_t pid, fpid; fpid = fork (); pid = getpid(); if (fpid > 0){ printf (" This is process(thread) %d. ",pid); y=1; } else if (fpid == 0){ sleep(1); printf (" This is process(thread) %d. ",pid); x=7; } else { printf ("fork failed "); return (1); } printf("x+y=%d ",x+y); }
