(Please disregard my first two similarly worded questions. This is the ammended version. Sorry for so many changes. Thank you.) Hello. Please look at the following code. When I run it from the command line, I am supposed to get the following results: 1: I am 1: I am I need to add a mutex lock to it so that the functions 'print_i' and 'print_j' print all of their lines. I compile it like so from the command line. cc –o lab6 lab6.c –pthread Any ideas? C source code: #include #include #include #include #include // These two functions will run concurrently void* print_i(void *ptr) { printf("1: I am \n"); sleep(1); printf("in i\n"); } void* print_j(void *ptr) { printf("2: I am \n"); sleep(1); printf("in j\n"); } int main() { pthread_t t1,t2; int rc1 = pthread_create(&t1, NULL, print_i, NULL); int rc2 = pthread_create(&t2, NULL, print_j, NULL); exit(0); }

Hello.
Please look at the following code. When I run it from the command line, I am supposed to get the following results:
1: I am
1: I am
I need to add a mutex lock to it so that the functions 'print_i' and 'print_j' print all of their lines. I compile it like so from the command line.
cc –o lab6 lab6.c –pthread
Any ideas?
C source code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <pthread.h>
#include <unistd.h>
// These two functions will run concurrently
void* print_i(void *ptr)
{
printf("1: I am \n");
sleep(1);
printf("in i\n");
}
void* print_j(void *ptr)
{
printf("2: I am \n");
sleep(1);
printf("in j\n");
}
int main() {
pthread_t t1,t2;
int rc1 = pthread_create(&t1, NULL, print_i, NULL);
int rc2 = pthread_create(&t2, NULL, print_j, NULL);
exit(0);
}
