Detailed Description

Portable spinlock class.

This class provides a portable "spinlock". It is implemented using the pthreads API on UNIX/Linux and the Win32 API on Microsoft Windows.

A spinlock can be used just like a mutex to protect access to critical data or code that is used by multiple threads. In some cases a spinlock may be more efficient than a mutex. But note that this class may be implemented using a mutex if there is no native support, which is currently the case on UNIX/Linux.

It is not necessary to use this class in order to use multiple threads with Open Inventor. It is provided only as a convenience. (However, note that you should use pthreads on UNIX/Linux and Win32 on Windows to be certain of compatibility with Open Inventor.)
