std::recursive_mutex (3) - Linux Man Pages
Defined in header <mutex>
class recursive_mutex; (since C++11)
The recursive_mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads.
recursive_mutex offers exclusive, recursive ownership semantics:
* A calling thread owns a recursive_mutex for a period of time that starts when it successfully calls either lock or try_lock. During this period, the thread may make additional calls to lock or try_lock. The period of ownership ends when the thread makes a matching number of calls to unlock.
* When a thread owns a recursive_mutex, all other threads will block (for calls to lock) or receive a false return value (for try_lock) if they attempt to claim ownership of the recursive_mutex.
* The maximum number of times that a recursive_mutex may be locked is unspecified, but after that number is reached, calls to lock will throw std::system_error and calls to try_lock will return false.
The behavior of a program is undefined if a recursive_mutex is destroyed while still owned by some thread. The recursive_mutex class satisfies all requirements of Mutex and StandardLayoutType.
