template <typename Mutex>struct MutexOps
Defined at line 25 of file ../../zircon/system/ulib/sync/include/lib/sync/internal/condition-template.h
A template implementation of a condition variable.
The algorithm is borrowed from MUSL.
The 'Condition' struct must contain the following fields:
int lock;
void* head;
void* tail;
The following struct template must be specialized for the mutex type 'Mutex'
in order to instantiate the template:
Public Methods
zx_futex_t * get_futex (Mutex * mutex)Return a pointer to the futex that backs the |mutex|
zx_status_t lock (Mutex * mutex, int * mutex_lock_err)Lock the |mutex|. If an error occurs while locking the mutex,
ZX_ERR_BAD_STATE must be returned. An implementation-defined
error code can be returned via |mutex_lock_err| if it's not null.
zx_status_t lock_with_waiters (Mutex * mutex, int waiters_delta, int * mutex_lock_err)Similar to lock(), but also update the waiter information in the mutex.
If the mutex implements waiter counting, then the count must be adjusted
by |waiters_delta|. Otherwise, the mutex must be marked as potentially
having waiters.
void unlock (Mutex * mutex)Unlock the mutex
void signal_requeue (sync_completion_t * completion, Mutex * mutex)Requeue all of the memebrs waiting in |completion| to the futex backing |mutex|.
