Detailed Description

lti mutex class

This object can be used to protect critical sections on multithreaded applications. The same thread should NOT try to lock the mutex more than once. The behavior of this will depend on the operating system: on linux/unix the thread will be locked forever (posix standard); on windows, the thread will count how many lock have been done, but it will not be blocked by the later locks!
