ssGetBusElementDataType

Get the data type identifier for a bus element

Syntax

int_T ssGetBusElementDataType(SimStruct* S, int_T busTypeID, int_T elemIdx)

Arguments

S

SimStruct that represents an S-Function block

busTypeID

The bus data type identifier that represents the bus signal

elemIdx

The zero-based bus element index

Returns

int_T

Description

Use to get the data type identifier for a specific bus element in a bus signal. Use the data type identifier to determine useful aspects of the bus element, including the number of elements (if this bus element is itself a bus signal) or the size of the data (ssGetDataTypeSize).

Languages

C, C++

Examples

static void mdlOutputs(SimStruct *S, int_T tid)
 {
    DTypeId    dType    = ssGetOutputPortDataType(S, 0);
    const void *u       = ssGetInputPortSignal(S, 0);
    int        numElems = ssGetNumBusElements(S, dType);
    int        i;
    
    for(i=0; i<numElems i++) {
        int_T elemType = ssGetBusElementDataType(S, dType, i);
 
      if (elemType == SS_DOUBLE) {
            /* Process signal here */
        } else {
            ...  
        }
     }
  }
