WebNov 10, 2024 · The second m.lock () breaks this requirement: C++11 30.4.1.2/7 Requires: If m is of type std::mutex or std::timed_mutex, the calling thread does not own the mutex. It looks like your implementation is able to detect that the calling thread owns the mutex and gives an error; others may block indefinitely, or fail in other ways. WebSep 16, 2024 · If the mutex is of the "recursive" type, the call to pthread_mutex_lock returns immediately with a success return code. The number of times the thread owning the mutex has locked it is recorded in the mutex. The owning thread must call pthread_mutex_unlock the same number of times before the mutex returns to the unlocked state.

WebThe timed_mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads. In a manner similar to mutex, timed_mutex offers exclusive, non-recursive ownership semantics. WebApr 10, 2012 · For this purpose, the standard library has a solution: std::timed_mutex and std::recursive_timed_mutex (if you need the recursivity properties of the mutex). You have access to the same functions as a std::mutex: lock() and unlock(), but you have also two new functions: try_lock_for() and try_lock_until(). The first one is also the most useful.
