S-function sampling time, is it possible to use several sampling time ?

Hi all,
I'm working with a C S-function. I want to call two different function at fixe frequenties. One every 125.06 µs and one at 250µs.
I have tried setting several sampling times :
ssSetSampleTime(S, 0, CONTINUOUS_SAMPLE_TIME);
ssSetOffsetTime(S, 0, 0.0);
ssSetSampleTime(S, 1 , 0.00012506 );
ssSetOffsetTime(S, 1 , 0.0);
ssSetSampleTime(S, 2 , 0.000250);
ssSetOffsetTime(S, 2 , 0.0);
And to call the functions I've been using:
if (ssIsSampleHit(S , 1, tid ))
function1()
if (ssIsSampleHit(S , 2, tid ))
function2()
But this does work at all, has someone got any idea how I can do ? The ssIsSampleHit doesn't seen to detect the right times.
Thank you,
George

I don't have much experience with multi-rate S-functions, but I thought I would recommend that you look at the demo sfcndemo_sfun_multirate.mdl. Just type the model name at the MATLAB prompt to open it up:
>> sfcndemo_sfun_multirate
Hopefully the example will give you some tips about how to use ssIsSampleHit.
