How to disable crash dumps programatically in c++?

Question

I'm writing a unit test application, where I want to make one of the methods to fail. For this I'm passing a NULL parameter to the method. But this is causing crash dump in the downstream. So how can we disable the crash dump generation through code?

I'm expecting there will be some registry setting for this, which can be changed through code.

I think the requirement here is incorrect. There are few signals which cannot be caught by the program itself. SIGSEGV ( which is raised when you access invalid memory / NULL ) is one among them. No operating system would expose an interface where you can control a SIGSEGV at the programs will. That would be very poor OS design.

It is best to rewrite the unit test which should just check for values ( as suggested by Joachim ), not crash the application. Crash tests come under system testing, and is not within the scope of unit testing.
