NAME

       SbMutex -

       A basic class for managing a mutex.

       This class provides a portable framework around the mutex interface of the underlying native thread-handling toolkit.

SYNOPSIS

       #include <Inventor/threads/SbMutex.h>

   Public Member Functions
       SbMutex (void)
       ~SbMutex ()
       int lock (void)
       SbBool tryLock (void)
       int unlock (void)

Detailed Description
       A basic class for managing a mutex.

       This class provides a portable framework around the mutex interface of the underlying native thread-handling toolkit.

Constructor &; Destructor Documentation
   SbMutex::SbMutex (void) [inline]
       Constructor.

   SbMutex::~SbMutex () [inline]
       Destructor.

Member Function Documentation
   int SbMutex::lock (void) [inline]
       This method locks the mutex. 0 is returned on success.

       If the mutex was previously unlocked, the thread will lock the mutex and continue running. If the mutex was already locked when this call
       is made, the thread will be suspended until the other thread holding the mutex releases it.

       This is a blocking operation.

   SbBool SbMutex::tryLock (void) [inline]
       This method tries to lock the mutex, and returns whether it was locked or not. This is a non-blocking operation.

   int SbMutex::unlock (void) [inline]
       This method unlocks the mutex.

NAME

       SbCondVar -

       A class for synchronizing access to global variables.

       Condition variables are used to protect global variables in an environment where multiple threads are running concurrently.

Detailed Description
       A class for synchronizing access to global variables.

Constructor &; Destructor Documentation
   SbCondVar::SbCondVar (void) [inline]
       Constructor.

   SbCondVar::~SbCondVar (void) [inline]
       Destructor.

Member Function Documentation
   SbBool SbCondVar::wait (SbMutex &mutex) [inline]
       This method blocks the calling thread until another thread calls wakeOne() or wakeAll() on the SbCondVar object.

   SbBool SbCondVar::timedWait (SbMutex &mutex, SbTimeperiod) [inline]
       This method blocks the calling thread until another thread calls wakeOne() or wakeAll() on the object, but if this does not happen within
       period, the thread is woken again anyways.

       TRUE is returned when the thread wakes because either wakeOne() or wakeAll() was called, FALSE is returned if the wait times out.

   void SbCondVar::wakeOne (void) [inline]
       This method wakes up one of the threads waiting on this SbCondVar.

   void SbCondVar::wakeAll (void) [inline]
       This method wakes up all the threads waiting on this SbCondVar.
