Get the name of a bus element

Syntax

const char* ssGetBusElementName(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

const char*

Description

Get the name of the bus element that you specify. Use ssGetBusElementName for error reporting or consistency checking.

Languages

C, C++

Example

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++) {
        const char *elemName = ssGetBusElementName(S, dType, i);
        
        if (strcmp(elemName, "control_signal") == 0) {
            ssSetErrorStatus(S, "No bus element named control_signal found");
        }
     }
  }
