24 | * Associating rt_OneStep with a real-time clock or interrupt service routine |
25 | * is what makes the generated code "real-time". The function rt_OneStep is |
26 | * always associated with the base rate of the model. Subrates are managed |
27 | * by the base rate from inside the generated code. Enabling/disabling |
28 | * interrupts and floating point context switches are target specific. This |
29 | * example code indicates where these should take place relative to executing |
30 | * the generated code step function. Overrun behavior should be tailored to |
31 | * your application needs. This example simply sets an error status in the |
32 | * real-time model and returns from rt_OneStep. |
