RWSynchObject

Base Class

#include <rw/sync/RWSynchObject.h>

RWSynchObject is the base class for synchronization classes, RWMutexLock, RWFIFOMutexLock, RWTRecursiveLock<Mutex>, RWSemaphore, RWCondition, RWReadersWriterLock, and RWCriticalSection. The class contains methods that support automatic cancellation detection for runnables containing a thread that is accessing the acquire or wait members of these derived classes.

enum RWCancellationState{
      RW_CANCELLATION_DISABLED,
      RW_CANCELLATION_ENABLED)};

Enumerated constants used to enable and disable automatic cancellation detection.

void
enableCancellation(void);

Turns on automatic cancellation detection.

void
disableCancellation(void);

Turns off automatic cancellation detection.

RWBoolean
isCancellationEnabled(void) const;

Determines whether automatic cancellation is enabled.

void
setCancellation(void);

Turns on automatic cancellation detection.

RWSynchObject(RWCancellationState
                state=RW_CANCELLATION_DISABLED);

Enforces that this class is used only as a base class.
