Specify whether an input port accepts frame data
#define MDL_SET_INPUT_PORT_FRAME_DATA void mdlSetInputPortFrameData(SimStruct *S, int_T port, Frame_T frameData)
This method is called with the candidate frame setting for an input port.
For C MEX S-functions, frameData is either FRAME_YES or FRAME_NO. If the proposed setting is acceptable, the method sets the actual frame data setting using ssSetInputPortFrameData. If the setting is unacceptable, the method generates an error via ssSetErrorStatus. Note that any other input or output ports whose frame data settings are implicitly defined by virtue of knowing the frame data setting of the given port can also have their frame data settings configured. This method is only valid for simulation, and must be enclosed in a #if defined(MATLAB_MEX_FILE) statement.
The Simulink® engine calls this method until all input ports with inherited frame settings have their frame settings specified.
The use of frame-based signals (mode has a value of 1 or frameData has a value of FRAME_YES) requires a DSP System Toolbox™ license.
