Writing S-Functions

ssGetOutputPortSignal

Get the vector of signal elements emitted by an output port.

Syntax

• void *ssGetOutputPortSignal(SimStruct *S, int_T port)
  

Arguments

S
   SimStruct representing an S-Function block.

port
   Index of an output port.

Description

Returns a pointer to the vector of signal elements output by port.

Note    If the port outputs a signal of type double (real_T), you must use ssGetOutputPortRealSignal to get the signal vector.

Example

Assume that the output port data types are int16_T.

•   nOutputPorts = ssGetNumOutputPorts(S);
    for (i = 0; i < nOutputPorts; i++) {
      int16_T *y      = (int16_T *)ssGetOutputPortSignal(S,i);
      int_T   ny      = ssGetOutputPortWidth(S,i);
      for (j = 0; j < ny; j++) {
          SomeFunctionToFillInOutput(y[j]);
      }
    }
