Thread Safety

[shemeshg]

what if there was a magical way to indicate that a function might be called from a thread and to warn me if I forget to use std::lock_guard<std::mutex> lock(mtx); if not atomic and is inout.

This is probably unrealistic, which is why Go has its channels to handle such scenarios.

Actually, just thought about it again, and all I need for that is a way to say.

//magical hint this block intended for multi-threading
myMapByRef[mystring] = "text123" //is is not guarded or atomic, I'll reject it.

but this is ok

//magical hint this block intended for multi-threading
std::lock_guard<std::mutex> lock(mtx);
myMapByRef[mystring] = "text123"
