Detailed Description
Simple convenience class for locking access to a function.
This class provides a simple convenience mechanism for automatically locking access to a function that is not re-entrant.
Usage example:
void myfunction(void) { SbThreadAutoLock lock(aMutexPtr); // [other code] }
In the class constructor, SbMutex::lock() is called on the mutex, and when the function exits (this is the convenience part) the destructor will automatically be invoked, calling SbMutex::unlock() on the same mutex.
Constructor & Destructor Documentation
SbThreadAutoLock::SbThreadAutoLock (SbMutex * mutex) [inline]

SbThreadAutoLock::SbThreadAutoLock (SbThreadMutex * mutex) [inline]
The constructor calls SbThreadMutex::lock() on mutex.
SbThreadAutoLock::~SbThreadAutoLock () [inline]
The destructor calls unlock() on the mutex passed in as a parameter to the constructor.
