1/**
2  | Helper class that locks a mutex on construction
3  | and unlocks the mutex when the destructor
4  | of the MutexLock object is invoked.
5  | 
6  | Typical usage:
7  | 
8  | -----------
9  | @code
10  | 
11  | c_void MyClass::MyMethod() {
12  |   MutexLock l(&mu_);       // mu_ is an instance variable
13  |   ... some complex code, possibly with multiple return paths ...
14  | }
15  |
