Hi Koldo,

In fact this helper class is intended to work with all sorts of mutexes: whatever you want as long as the methods 'lock' and 'unlock' exist.

The code is therefore 'portable'... but it can't be used directly in Upp since the methods 'lock' & 'unlock' are called 'Enter' and 'Leave'
The reason why I did this is to make 'POLICY BASED DESIGN' code:
http://en.wikipedia.org/wiki/Policy-based_design
http://loki-lib.sourceforge.net/index.php?n=Main.Policy-base dDesign

In you're case, just use

Mutex::Lock( <you're mutex> )

It should do what you need.

Quote:

The Mutex::Lock class that Mirek mentioned, creates a temporary mutex

This is not true, a reference is used so the behavior is exactly the same as my template.
