module Control: Duppy.Monad.Mutex.Mutex_control

val create : unit -> mutex

create () creates a mutex.

val lock : mutex -> (unit, 'a) Duppy.Monad.t

A computation that locks a mutex and returns unit afterwards. Computation will be blocked until the mutex is sucessfuly locked.

val try_lock : mutex -> (bool, 'a) Duppy.Monad.t

A computation that tries to lock a mutex. Returns immediatly true if the mutex was sucesfully locked or false otherwise.

val unlock : mutex -> (unit, 'a) Duppy.Monad.t

A computation that unlocks a mutex. Should return immediatly.
