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 { ... } } }
