Detailed Description

template<typename Callback>
class agxUtil::OnScopeExit< Callback >

Register a callback to be called at the end of the current scope.

The callback may not throw exceptions, std::terminate may be called immediately if it does.

The callback should not take any parameters. The return value is ignored.

A factory function, onScopeExit, is provided to make OnScopeExit using lambdas possible.

Example usage:

void myFunction() { FILE* myFile = fopen(....); const auto& closeFile = onScopeExit([myFile]() { fclose(myFile); }); std::ignore = closeFile; std::ignore is used to prevent warning about unused variable.

The rest of the function goes here, possibly with early returns or exception throwing. }
