16       Locks for mutual exclusion.
17
18       Mutexes  (mutual-exclusion  locks)  are used to implement critical sec‐
19       tions and protect shared mutable  data  structures  against  concurrent
20       accesses.   The  typical  use is (if m is the mutex associated with the
21       data structure D ): Mutex.lock m; (*  Critical  section  that  operates
22       over D *); Mutex.unlock m

42       val lock : t -> unit
43
44       Lock  the given mutex. Only one thread can have the mutex locked at any
45       time. A thread that attempts to lock a mutex already locked by  another
46       thread will suspend until the other thread unlocks the mutex.

50       val try_lock : t -> bool
51
52       Same  as  Mutex.lock  ,  but does not suspend the calling thread if the
53       mutex is already locked: just return false immediately in that case. If
54       the mutex is unlocked, lock it and return true .

58       val unlock : t -> unit
59
60       Unlock  the  given  mutex.  Other  threads suspended trying to lock the
61       mutex will restart.
