The following example opens manual enrollment for a compound assembly
with four selectors. The isiGetWidth() returns the library’s default value. In
this example, enrollment is being opened in response to the user pressing a
Connect button. Enrollment can only be opened when the ISI engine is in the
normal state. The ProcessIsiButton() function is called in response to the
Connect button being pressed:
IsiEvent isiState;
void IsiCreateCsmo(....) {
// set pCsmoData as desired
}
unsigned IsiGetWidth(unsigned Assembly) {
return Assembly == myAssemblyNumber ?
4 : isiGetWidth(Assembly);
}
void ProcessIsiButton(unsigned Assembly) {
switch(isiState)
{
...
case
isiNormal:
IsiOpenEnrollment(Assembly);
break;
... //Processing for other states
} // end of switch(state)
}

The following example opens controlled enrollment for a compound assembly
with four selectors. The isiGetWidth() returns the library’s default value:
IsiEvent isiState;
void IsiCreateCsmo(....) {
// set pCsmoData as desired
}
unsigned IsiGetWidth(unsigned Assembly) {
return Assembly == myAssemblyNumber ?
4 : isiGetWidth(Assembly);
}
void sendControlResponse(boolean success) {
IsiMessage ctrlResp;
ctrlResp.Header.Code = isiCtrp;
ctrlResp.Ctrp.Success = success;
memcpy(ctrlResp.Ctrp.NeuronID,
read_only_data.neuron_id, NEURON_ID_LEN);
resp_out.code = isiApplicationMessageCode;
memcpy(resp_out.data, &ctrlResp,
sizeof(IsiMessageHeader)+sizeof(IsiCtrp));
resp_send();
