Question

Question 1 (1 points): Consider the following C program that uses the POSIX API: void thread_function(void argument) { const char ptr = (const char) argument; write(STDOUT_FILENO, ptr, strlen(ptr)); return NULL; } int main(int argc, const char **argv) { pthread_t a, b; pthread_create(&a, NULL, thread_function, (void) "A"); pthread_create(&b, NULL, thread_function, (void) "B"); pthread_join(&a, NULL); write(STDOUT_FILENO, "C", 1); pthread_join(&b, NULL); return 0; } Assume none of the calls to pthread_create, pthread_join, or writefail (and ignore minor syntax errors, missing #includes, etc.). Which of the following are possible outputs of this code? Select all that apply A. BAC B. ACB C. ABC D. BCB E. BCA F. AC

Question 1 (1 points): Consider the following C program that uses the POSIX API:
void *threadfunction(void *argument)
const char *ptr = (const char*) argument;
write(STDOUTFILENO, ptr, strlen(ptr));
return NULL;

int main(int argc, const char **argv)
