ssSetInputPortUnit

Specify unit of input port

Syntax

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

Arguments

S: SimStruct representing 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++

Example

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

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