Member Function Documentation

lock()

void mysql::concurrency::Mutex_wrapper::lock ( )

noexcept

Acquire a lock, blocks access to a critical section until "unlock" is called.

native_handle()

decltype(auto) mysql::concurrency::Mutex_wrapper::native_handle ( )

inline

Returns the native handle of the mutex.

Returns

Reference to the underlying mysql_mutex_t object

operator=() [1/2]

Mutex_wrapper & mysql::concurrency::Mutex_wrapper::operator= ( const Mutex_wrapper &  src )

delete

operator=() [2/2]

Mutex_wrapper & mysql::concurrency::Mutex_wrapper::operator= ( Mutex_wrapper &&  src )

delete

try_lock()

bool mysql::concurrency::Mutex_wrapper::try_lock ( )

noexcept

Non-blocking try-lock operation.

Return values

true	Lock has been acquired
false	Lock has NOT been acquired

unlock()

void mysql::concurrency::Mutex_wrapper::unlock

(

)

Unblocks access to a critical section for other threads.
