SbThreadAutoLock Class Reference
[Portable Threads Abstraction Classes]

#include <Inventor/threads/SbThreadAutoLock.h>

List of all members.


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.

Public Member Functions
