13\ingroup Base
14
15This class implements a mutex interface. The actual work is done via
16TMutex which is available as soon as the thread library is loaded.

18and
19
20TLockGuard
21
22This class provides mutex resource management in a guaranteed and
23exception safe way. Use like this:
24~~~ {.cpp}
25{
26 TLockGuard guard(mutex);
27 ... // do something
28}
29~~~
30when guard goes out of scope the mutex is unlocked in the TLockGuard
31destructor. The exception mechanism takes care of calling the dtors
32of local objects so it is exception safe.
