Function except_failure

boost::contract::except_failure — Call failure handler for exception guarantees.

Synopsis

// In header: <boost/contract/core/exception.hpp>


void except_failure(from where);

Description

This is often called only internally by this library.

Throws: This can throw in case programmers specify a failure handler that throws exceptions on contract assertion failures (not the default), however:

[Warning] Warning

When this failure handler is called there is already an active exception (the one that caused the exception guarantees to be checked in the first place). Therefore, programming this failure handler to throw yet another exception will force C++ to automatically terminate the program.

See Also:

Throw on Failure, Exception Guarantees

Parameters:

where

Operation that failed the contract assertion.
