The difference between critical section and mutex in "original" multithreaded programming

The difference between a critical section and a mutual exclusion lock
1. The critical section can only be used for mutually exclusive access between threads in the same process, and mutexes can be used for mutually exclusive access between object processes or threads.
2, the critical area is a non-kernel object, only in the user state to lock operation, fast , the mutex is the kernel object, in the nuclear mentality of the lock operation , slow speed .
3. Critical section and mutex are available under Windows platform; only mutexes are available under Linux
