The original win32 port of class Mutex was as a critical section, so the terminology got back-ported :).

Furthermore,
ost::Mutex has EnterMutex() and LeaveMutex()

I mean, you enter and leave a critical section, but you lock and unlock a mutex... ThreadLock seemed to have it right there... Am I wrong here? :)


I'm a stickler for names, myself.... I can't explain it, but I think things should always be named most appropriately...

Well, it does seem a strange choice since we dont have a "ThreadMutex". Perhaps RWLock would have been better...

Older and poorer compilers have different problems. For example, if you define a class foo in a common header that uses STL, and have an instance of foo in test1.cpp and in test2.cpp, you may have template generated object code in both test1.o and test2.o even when it has been subroutined and is identical/duplicate function calls. Newer compilers and linkers throw away duplicate code like this. Then there was a time not all c++ compilers could compile STL...

My mistake, I meant "ThreadLock" when I said RWLock :). That's why you can't find it....

As for realpath, I think it would have to provide an implimentation if one is not provided. realpath is far too useful for enforcing path restricted access policies.




What is the significance of the name 'ThreadLock'... 'RWLock' seems to make much more sense... And there may even be a better term from a CS textbook.
