NAME
SbRWMutex
SYNOPSIS
#include <Inventor/threads/SbRWMutex.h>
Detailed Description
The SbRWMutex is a mutex that i sused 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. - Public Types
- enum Precedence { READ_PRECEDENCE, WRITE_PRECEDENCE }
- Public Member Functions

Member Function Documentation
- int SbRWMutex::writeLock (void) [inline]
- This method blocks the calling thread until it gains write lock status on the SbRWMutex object.
- Referenced by SoDB::writelock().
- 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.
- Referenced by SoDB::writeunlock().
- int SbRWMutex::readLock (void) [inline]
- This method blocks the calling thread until it gains read lock status
on the SbRWMutex object. - Referenced by SoDB::readlock().
- 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.
- Referenced by SoDB::readunlock().
