~scoped_lock()
Destroy lock. If holding a lock, releases the lock first.
Base class for types that should not be copied or assigned.
static const bool is_recursive_mutex
__TBB_Flag my_unlock_value
Value to store into spin_mutex::flag to unlock the mutex.
A lock that occupies a single byte.
__TBB_Flag __TBB_LockByte(__TBB_atomic_flag &flag)
__TBB_atomic_flag flag
0 if lock is released, 1 if lock is acquired.
void __TBB_EXPORTED_METHOD internal_release()
Like release, but with ITT instrumentation.
spin_mutex * my_mutex
Points to currently held mutex, or NULL if no lock is held.
void __TBB_EXPORTED_METHOD internal_acquire(spin_mutex &m)
Like acquire, but with ITT instrumentation.
scoped_lock(spin_mutex &m)
Construct and acquire lock on a mutex.
void __TBB_EXPORTED_METHOD internal_construct()
Internal constructor with ITT instrumentation.
void unlock()
Release lock.
void acquire(spin_mutex &m)
Acquire lock.
bool __TBB_TryLockByte(__TBB_atomic_flag &flag)
bool __TBB_EXPORTED_METHOD internal_try_acquire(spin_mutex &m)
Like try_acquire, but with ITT instrumentation.
Represents acquisition of a mutex.
scoped_lock()
Construct without acquiring a mutex.
void const char const char int ITT_FORMAT __itt_group_sync s
void suppress_unused_warning(const T1 &)
Utility template function to prevent "unused" warnings by various compilers.
__TBB_atomic __TBB_Flag __TBB_atomic_flag
void release()
Release lock.
bool try_acquire(spin_mutex &m)
Try acquiring lock (non-blocking)
bool try_lock()
Try acquiring lock (non-blocking)
interface7::internal::padded_mutex< spin_mutex, false > speculative_spin_mutex
A cross-platform spin mutex with speculative lock acquisition.
static const bool is_rw_mutex
#define __TBB_DEFINE_PROFILING_SET_NAME(sync_object_type)
#define __TBB_EXPORTED_METHOD
spin_mutex()
Construct unacquired lock.
static const bool is_fair_mutex
