Detailed Description

RAII wrapper that spin-waits to claim a critical section.

Unlike OSCriticalSectionObj (which blocks the calling task), this class repeatedly calls EnterNoWait() on the OS_CRIT object until the section is successfully claimed. This allows the scheduler to continue running the task between attempts. On destruction, Leave() is called to release the critical section.

Note

Use this only when you expect the critical section to be held for very brief periods. For longer holds, prefer OSCriticalSectionObj.
