Hi,

It does seem that you are not using "call" properly.
Have a look at the examples in Scilab Help >> Link dynamique/incremental 
 > call
You basically need to know and tell "call", for each input argument:
- its position in the function call: ret=function(a,b,c): a: position 1, 
b: position 2,c: position 3.
- its type and dimension.
You also have to do the same for the output argument.

If you give us the prototype of the C function you are trying to call, 
we might try to get the right call sequence.

Cheers,

Antoine
