S-Function using printf in mdlStart

I would like to debug my S-Function C code using "printf", but why the mdlStart is not able to print anything out?

static void mdlInitializeSizes {
printf("mdlInitSizn");
}

static void mdlInitializeSampleTimes {
printf("mdlInitTime\n");
}

static void mdlStart(SimStruct *S) {
printf("mdlStart\n");
}

static void mdlOutputs {
print("mdlOutputs\n");
}

OUTPUT:

mdlInitSiz

mdlInitTime

mdlOutputs

mdlOutputs

...

do not include stdio.h in your code, it will re-target the standard io functions. it will work
