WebMar 27, 2024 · C++17 introduced a shared_mutex implementation that is now available in most C++ compilers. While a regular mutex exposes 3 methods: lock, unlock and try_lock, a shared_mutex adds 3 more: lock_shared, unlock_shared, try_lock_shared. The first 3 methods work exactly the same as in a regular mutex. i.e. WebFeb 24, 2024 · You can use a mutex object to protect a shared resource from simultaneous access by multiple threads or processes.
