Inlining an S-Function

Without a TLC file to define the S-function specifics, RTW must call the

MEX-file S-function in a manner similar to RTW 1.3. That is, the execution of

the S-function is through the S-function API.

void

MdlStart()

{

/* S-Function block: foo */

{

SimStruct *s = ssGetSFunction(S, 0);

real_T *sfcnX = ssGetX(s);

sfcnInitializeConditions(sfcnX, s);

}

Unnecessary call to

empty function

mdlInitializeCondition

in foogain.c.
