Multithreading with mutexes and time constraints Hi everyone, I am writing a server and I need to generate chunks of the world and access them in other threads. The initialization may take a while (seconds), but I need the other threads to be faster than that (basically realtime). My idea is to use multiple mutexes per chunk, an InitMutex and a ModifyMutex. When initializing (pseudocode): Lock InitMutex; Initialize the chunk; Lock ModifyMutex; Set status "initialized"; Unlock both mutexes; When reading/modifying: Lock ModifyMutex; If status is "initialized": Perform operations on chunk data; Unlock ModifyMutex; Does this work? Will the thread that only locks the ModifyMutex see the data written by the initialization thread? In the standard it says: Does that mean that the initialization of the chunk data is synchronized when ModifyMutex is locked on the modifying thread because it occured before ModifyMutex was unlocked?
