Detailed Description

template<class T>
struct Janitor< T >

Simple utility class for running a cleanup function during stack unwinding.

This is useful in wrapping C APIs where resources are managed with acquisition and release functions. In that case, you can create a Janitor<SomeType> with a pointer to the C release function, so that the release function will be automatically called when the enclosing scope is exited (whether by function return or by exception propagation).
