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]

The constructor calls SbMutex::lock() on mutex.

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.
