Is there a favored idiom for mimicing Java's try/finally in C++?

Question

Been doing Java for number of years so haven\'t been tracking C++. Has finally clause been added to C++ exception handling in the language definition?<

Answer 1

To avoid having to define a wrapper class for every releasable resource, you may be interested in ScopeGuard (http://www.ddj.com/cpp/184403758) which allows one to create "cleaners" on the fly.

For example:

FILE* fp = SomeExternalFunction();
// Will automatically call fclose(fp) when going out of scope
ScopeGuard file_guard = MakeGuard(fclose, fp);
