Just like Inputs and Outputs there are S-function APIs to access the parameters.

Please check

S-function Parameters

ssGetSFcnParam

ssSetNumSFcnParams

ssGetSFcnParamDataType

Thank you for sharing the API info.

I have seen the S function API's , if i execute below code , unable to get the index of selected popup

seudo code to get index of the selected options(CAN1,CAN2 popup options)

#define CAN_PARM(S) ssGetSFcnParam(S,0)

static void mdlOutputs(SimStruct *S, int_T tid)

{

int_T data;

const mxArray* mx = CAN_PARM(S);

int channel = (int)mxGetScalar(mx);

switch(channel)

{

case 0: data= CAN1; break; //CAN1 and CAN2 are enums

case 1: data= CAN2; break;

}

}

please tell me how to resolve this problem.

Thank you in advance

Have you tried with S-function builder ?

Add your parameters in S-function builder and generate the s-function.

Generated s-function will have correct code to access the parameters. You can use that code as a reference.

I have tried with S-function builder, Added popup Mask parameter for S-function builder and built the S-function. it has created .c and .tlc file but it does not have code of popup Mask parameter.
