/* Associating rt_OneStep with a real-time clock or interrupt service routine

* is what makes the generated code "real-time". The function rt_OneStep is

* always associated with the base rate of the model. Subrates are managed

* by the base rate from inside the generated code. Enabling/disabling

* interrupts and floating point context switches are target specific. This

* example code indicates where these should take place relative to executing

* the generated code step function. Overrun behavior should be tailored to

* your application needs. This example simply sets an error status in the

* real-time model and returns from rt_OneStep.
