There is an example model and an S-function that you can download below.
You will have to compile the S-function using the following command:
mex fileout2.c
This example file will write every 10th data point to the file. A DWork vector is used to keep count of the number of data points.You should take a look at the mdlStart Callback that opens a file and then gets a pointer to the file. You should also take a look at the mdlTerminate Callback that will close the file.
