Hi.

A mutex requires some memory space to function, that memory can be
allocated on the heap or on the stack, if its on the stack then
you'll use a static mutex and initialize it to the right value.

Typically you'll use a static mutex in a reentrant function that has
a critical section to protect, a mutex on the heap on the other hand
is usually used to protext a specific resource that is shared and
accessible throughout program execution (in which case you need
to expose and share the mutex object allocated on the heap as well).
