ssGetNumBusElements

Get the number of elements in a bus signal

Syntax

int_T ssGetNumBusElements(SimStruct *S, int_T busTypeID)

Arguments

S: SimStruct that represents an S-Function block
busTypeID: The bus data type identifier that represents the bus signal

Returns

int_T

Description

Use to determine the number of elements in the bus. If one of the elements is also a bus signal, usessGetNumBusElementsrecursively to determine the number of elements in the sub-bus signal. The second argument is the identifier that Simulink^®returns after you register the bus object that represents the bus signal. (To register a bus object, usessRegisterTypeFromParameteror an equivalent method.)

Languages

C, C++

Example

静态孔隙mdlOutputs (SimStruct *年代,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
