Module Mutex
Locks for mutual exclusion.
Mutexes (mutual-exclusion locks) are used to implement critical sections and protect shared mutable data structures against concurrent accesses. The typical use is (if m
is the mutex associated with the data structure D
):
Mutex.lock m;
(* Critical section that operates over D *);
Mutex.unlock m
val create : unit -> t
Return a new mutex.
val lock : t -> unit
Lock the given mutex. Only one thread can have the mutex locked at any time. A thread that attempts to lock a mutex already locked by another thread will suspend until the other thread unlocks the mutex.
val try_lock : t -> bool
Same as Mutex.lock
, but does not suspend the calling thread if the mutex is already locked: just return false
immediately in that case. If the mutex is unlocked, lock it and return true
.
val unlock : t -> unit
Unlock the given mutex. Other threads suspended trying to lock the mutex will restart.
