c++ - Issue unused parameter warnings in XCode -

-

I am using XcodeDA 6.0.1 (6A317) with Mac OS X Mavericks. In my C ++ project, I recently discovered a bug that could be detected by the fact that I forgot to use any parameter of the function. For example, the following functions should result in two warnings (for two unused criteria): 

  int main (integer argc, const char * argv []) {return 0; Open the build settings of your project In the search field at the top, click the "Unused" enter the. 
 
 You will see several matching settings under warnings. One of them is the unused parameter, turn it on.

Registering an Interceptor For All Interface Implementaions in Castle Windsor -

-
I'm quite new to the castle and especially to the Windsor using Interceptors and if it's all across a It is possible to register the interceptor, in return, instead of specifying each implementation, implementing a particular interface. For example, I have an interface called IComponent , which will be implemented by multiple classes. I have a ComponentInterceptor class written to work on these classes when they have performed a particular method, I want to do something like this: _container Register (Component.For & LT; IComponent & gt; () .Interceptors ("ComponentInterceptor") .LifestyleSingleton ()) Rather than what to do: _container.register (Component.For & lt; IComponent & gt; ().

ImplementedBy & LT; ComponentB & gt; () .Interceptors (...
