Question

What will be the result of a thread executing the following C code snippet?
 lock_t mutex;
.
.
.
lock(&mutex);
while(1){
myFunc();
}
unlock(&mutex);

Answer

Since hardware provides atomicity of instructions within locks, myFunc will completely take over a single CPU and repeatedly execute indefinitely.

Answer

Other processes/threads will be able to run as the scheduler determines, but no other thread will ever be able to enter this critical section when running on the same CPU core as thread currently holding the lock mutex since it will never be released.

Answer

Since hardware provides atomicity of instructions within locks, myFunc will completely take over all CPU cores and repeatedly execute indefinitely.

Answer

Other processes/threads will be able to run as the scheduler determines, but no other thread will ever be able to enter this critical section when running on any CPU core as the lock mutex will never be released.
