The RaiseException Windows function will throw an SEH exception. The first parameter is the exception code and the second indicates if the process can continue after this exception is handled (0 means it can). The third and fourth parameters give additional information about the exception. The fourth parameter is a pointer to an array with these additional parameters and the number of parameters is given in the third parameter.
