Compliant Code Example (Visual Studio 2008
...
and later)
Although the ISO/IEC TR 24731-1 functions were created by Microsoft, currently available versions of Microsoft Visual Studio do does not support the same interface defined by the technical report for installing runtime-constraint handlers. Visual Studio calls these functions "invalid parameter handlers," and they are installed by calling the _set_invalid_parameter_handler() function. The signature of the handler is also significantly different [MSDN].
