-- The Simulink API for Ada S-Function

with Simulink; use Simulink;

package Times_Two is

   -- The S_FUNCTION_NAME has to  be defined as a constant string.  Note that
   -- the name of the  S-Function (ada_times_two) is different  from the name
   -- of this package (times_two).  We do this so that it is easy to identify
   -- this example S-Function in the MATLAB workspace. Normally you would use
   -- the same name for S_FUNCTION_NAME and the package.
   --
   S_FUNCTION_NAME : constant String := "ada_times_two";

   -- Every S-Function is required to have the "mdlInitializeSizes" method.
   -- This method needs to be exported as shown below, with the exported name
   -- being "mdlInitializeSizes".
   --
   procedure mdlInitializeSizes(S : in SimStruct);
   pragma Export(C, mdlInitializeSizes, "mdlInitializeSizes");

   procedure mdlOutputs(S : in SimStruct; TID : in Integer);
   pragma Export(C, mdlOutputs, "mdlOutputs");
