How do I read the system clock using a C-MEX S-Function on the target PC using xPC Target?

I would like to be able to read the system clock using a Level-2 C-MEX S-Function on the target PC using xPC Target.

The xPC Target documentation does not describe how to read the system clock in a C-MEX S-Function on the target PC. The attached model has an S-function that illustrates how to do this.

1. Download the attached files "xpcosctimeofday.mdl" and "xpctimeofday2.c" and place them in your MATLAB working directory.

2. MEX the C-file using the following command

mex xpctimeofday2.c

3. Build and download the model to the target PC. Execute the model on the target PC.

The scope of type target should display the system time on the target PC monitor.

4. Examine the "xpctimeofday2.c" file for details on how the system time was obtained in the S-function.
