std::shared_lock
Member functions
Shared locking
shared_lock::try_lock
Modifiers
Observers
Non-member functions
bool try_lock();
(since C++14)
Tries to lock the associated mutex in shared mode without blocking. Effectively calls mutex()->try_lock_shared().
std::system_error is thrown if there is no associated mutex or if the mutex is already locked.
[edit] Parameters
(none)
[edit] Return value
true if the ownership of the mutex has been acquired successfully, false otherwise.
[edit] Exceptions
- Any exceptions thrown by mutex()->try_lock_shared().
- If there is no associated mutex, std::system_error with an error code of std::errc::operation_not_permitted .
- If the mutex is already locked, std::system_error with an error code of std::errc::resource_deadlock_would_occur .
