Hello Koldo,

A mutex is used to protect a variable from being modified by two threads at the same time (no matter how that variable is modified).
So if you modify a variable using the var itself or a pointer to it: the result is the same ==> you have to protect the variable

If the variable is accessed by only one thread, then there is no need to use mutexes
