Function EnterCriticalSection

EnterCriticalSection locks a Win32 critical section. If the calling thread must block, RTKWait is called on the RTKernel-32 semaphore associated with the given critical section.

Unlike Windows, RTKernel-32 will implicitly initializes a critical section by calling InitializeCriticalSection if an uninitialized critical section is supplied as a parameter (that is, a structure with all fields set to zero). Thus, calling InitializeCriticalSection is never required. Merely heap-allocated critical sections should be be memset to zero before use. Auto-initializing critical sections is multithread and multiprocessor safe.
