Ensuring that Exceptions are always Caught *

Question

Exceptions in C++ don't need to be caught (no compile time errors) by the calling function. So it's up to developer's judgment whether to catch it using try/catch (unlike in Java).

Is there a way one can ensure that the exceptions thrown are always caught using try/catch by the calling function?

Answer

No.

See A Pragmatic Look at Exception Specifications for reasons why not.

The only way you can "help" this is to document the exceptions your function can throw, say as a comment in the header file declaring it. This is not enforced by the compiler or anything. Use code reviews for that purpose.
