Releases all resources used by an unowned critical section object.
void DeleteCriticalSection( LPCRITICAL_SECTION lpCriticalSection );
A pointer to the critical section object. The object must have been previously initialized with the InitializeCriticalSection function.
This function does not return a value.
Deleting a critical section object releases all system resources used by the object. The caller is responsible for ensuring that the critical section object is unowned and the specified CRITICAL_SECTION structure is not being accessed by any critical section functions called by other threads in the process.
After a critical section object has been deleted, do not reference the object in any function that operates on critical sections (such as EnterCriticalSection, TryEnterCriticalSection, and LeaveCriticalSection) other than InitializeCriticalSection and InitializeCriticalSectionAndSpinCount. If you attempt to do so, memory corruption and other unexpected errors can occur.
If a critical section is deleted while it is still owned, the state of the threads waiting for ownership of the deleted critical section is undefined.
