Detailed Description
RAII object for disabling, then restoring, interrupt state Usage:
// RAII style usage unsigned int atomic_counter_increment(unsigned int &counter) { CriticalSectionLock lock; // Code in this block will run with interrupts disabled // Interrupts will be restored to their previous state automatically // at the end of function scope return ++counter; } // free locking usage unsigned int atomic_counter_decrement(unsigned int &counter) { CriticalSectionLock::enable(); // Code in this block will run with interrupts disabled counter--; CriticalSectionLock::disable(); // need explicitly to disable critical section lock // interrupts will be restored to their previous state here return counter; }
