ssSetInputPortUnit

Specify unit of input port

Syntax

UnitId ssSetInputPortUnit(SimStruct *S, int_T port, UnitId id);

Arguments

S

SimStruct that represents an S-Function block.

port

Index of an input port.

id

ID of the unit accepted by port. This ID is returned from the ssRegisterUnitFromExpr method.

Returns

The unit ID specified by id. Returns -1 if id is DYNAMICALLY_TYPED.

Description

Use in mdlInitializeSizes (after ssSetNumInputPorts) to specify the unit for each input port. Input port index numbers start at 0 and end at the total number of input ports minus 1 (0 to total number of input ports - 1).

Languages

C, C++

Examples

UnitId id = INVALID_UNIT_ID; 
ssRegisterUnitFromExpr(S , "m/s" , &id); 
if (id == INVALID_UNIT_ID) return; 

ssSetInputPortUnit(S, portIdx, id); 
ssSetOutputPortUnit(S, portIdx, id);
