funptr - coding of primitives ( wizard stuff )
Utility function (for experts only) to get the internal routine number numptr of the primitive 'name' . numptr is formed from the interface number fun and the routine number fin of the primitive in its interface by numptr = 100*fun + fin (fin < 100). From numptr you can get the interface number fun = floor(numptr/100) which may be useful to link a dynamical interface with arguments passed by reference (see example section).
// Suppose you want to load some codes via the dynamic // loading facilities offers by addinter. By default // arguments are passed by values but if you want to // pass them by reference you can do the following // (name being the scilab name of one of the interfaced // routines) : // // addinter(files,spnames,fcts) // args passed by values // num_interface = floor(funptr(name)/100) // intppty(num_interface) // args now passed by reference // // Note that if you enter the following // // intppty() // // you will see all the interfaces working by reference
