Writing S-Functions

mdlSetInputPortWidth

Set the width of an input port that accepts 1-D (vector) signals.

Syntax

• void mdlSetInputPortWidth(SimStruct *S, int_T port, int_T width)
  

Arguments

S
   SimStruct representing an S-Function block.

port
   Index of a port.

width
   Width of signal.

Description

This method is called with the candidate width for a dynamically sized port. If the proposed width is acceptable, the method should go ahead and set the actual port width using ssSetInputPortWidth. If the size is unacceptable, an error should be generated via ssSetErrorStatus. Note that any other dynamically sized input or output ports whose widths are implicitly defined by virtue of knowing the width of the given port can also have their widths set via calls to ssSetInputPortWidth or ssSetOutputPortWidth.
