call C function in Scilab 5.0.2

[Sébastien Barré]

Dear Scilab users / Developpers,

I am currently working on the development of an interface between 
measurement devices and the great Scilab machine.
The idea is to be able to command the devices connected to the computer 
directly for the scilab command Line.

In this aim, I use the Scilab c_link function to link c function of a DLL,
then the Scilab call function.

It looks like this:

if (~c_link('QueryDevices'))
funcload = ['QueryDevices'];
link('SCILabIF.dll', funcload, 'c');
end

[NbrOfDevices] = call('QueryDevices', 'out', [1,1], 1, 'i');
if (NbrOfDevices <= 0) //error handling no devices found
  rc = -1;
end


My problem is:

The command:
[Name, Channels] = call('GetChannelName',  0 , 1, 'i', 'out', [32, 1], 
2, 'c', [1,1], 3, 'i');

works properly with version 4.1.2 of Scilab, but with Version 5.0.2 I 
get the message

Warning !!!
Scilab has found a critical error (EXCEPTION_ACCESS_VIOLATION)
with "call" function.
Save your data and restart Scilab.
 
Warning: stack problem..., cleared.



Does anybody  know  why? and how could I solve it.

Thanks in advance,

Sébastien
