Structure of the S-Function
The following diagram shows the basic structure of an S-function that directly handles fixed-point data types.
The callouts in the diagram alert you to the fact that you must include
fixedpoint.h
and fixedpoint.c
at the
appropriate places in the S-function. The other elements of the S-function displayed in
the diagram follow the standard requirements for S-functions.
