Detailed DescriptionThe SbRWMutex is a mutex that is used to grant both read and write access to the data it protects​. Multiple threads can have read locks on the data at once, but only one write-lock can be given out and not while a thread has a read lock on the data​. The policy on granting read locks to threads when a thread is waiting for the write lock is something that should be configurable at construction time but which isn't at the moment​.

Member Function Documentation
int SbRWMutex::writeLock (void) [inline]This method blocks the calling thread until it gains write lock status on the SbRWMutex object​.
SbBool SbRWMutex::tryWriteLock (void) [inline]This method tries to gain write lock status on the SbRWMutex​. TRUE is returned if it was successful, FALSE otherwise​. This is a non-blocking operation​.
int SbRWMutex::writeUnlock (void) [inline]This method is used for unlocking the calling thread's write lock​.
int SbRWMutex::readLock (void) [inline]This method blocks the calling thread until it gains read lock status on the SbRWMutex object​.
SbBool SbRWMutex::tryReadLock (void) [inline]This method tries to gain read lock status on the SbRWMutex​. TRUE is returned if it was successful, FALSE otherwise​. This is a non-blocking operation​.
int SbRWMutex::readUnlock (void) [inline]This method is used for unlocking the calling thread's read lock​.
