[Scilab-Dev] Evolution of Scilab API

[Antoine ELIAS]

Hello,

First one ( API 1 ) was write to be "compatible" between Scilab 5 and 
Scilab 6. ( except last arg, int -> void*, sorry about that )
So in Scilab 6 we reproduce stack behavior ( Top, Rhs, LhsVar(x) = y), 
but that produce lot of copy, move of data).
The second ( API 2 ) is the nearest from internal memory of Scilab 6.

@Stéphane: Both API can be used, we don't plan to remove API 1.

@Arvid:
Did you take a look of SCI/contrib/toolbox_skeleton/sci_gateway/c ? 
(http://cgit.scilab.org/scilab/tree/scilab/contrib/toolbox_skeleton/sci_gateway/c?h=6.0.0)
I wrote same gateways with API 1 and API 2.

Regards,
Antoine
