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);
}
