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.

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]);
    }
  }
