Can a Windows CRITICAL_SECTION object be configure

问题:

By default, a CRITICAL_SECTION object is recursive. Can this behaviour be configured like a pthread mutex to enable or disable recursive thread access?

To clarify in response to the comments: I am referring specifically to a Windows CRITICAL_SECTION object, not a Windows mutex.

回答1:

No, it cannot. Documented APIs do not mention this in any way. Windows critical sections always accept recursive access.



回答2:

A Critical Section always allows recursion within a thread. So does a Mutex. That is by design and cannot be changed.

A Semaphore, on the other hand, can prevent recursion within a thread. See MSDN documentation for more details.
