Yeah! Bert:
It works perfectly if I use char* and
self apiSetOption: handle option: bla value: 'aStringValue'
If I use void* and
self apiSetOption: handle option: bla value: 'aStringValue' asByteArray
it seems it doesn't arrives well to the library.
many thanks,
mariano

The first argument appears to be a pointer to a handle object. You probably should not declare that as ulong if you then pass "self" (which I assume is a ExternalStructure subclass). But that depends on how you acquire the handle, and how you represent it in the image.
Yes you are right, sorry. It was not self, but a attribute called handle. My mistake.
The argument to void* should be a ByteArray or WordArray, methinks, I'd try "WordArray with: 1" if you want to pass a pointer to the Integer 1.

Sounds interesting. I will test it and then I tell you.
Bert: I test this using WordArray and I work perfect in all the cases the value was a number. But the type in the function definition is void*. So, now, I need to send not only a 1 or 0, but a String. In this case, I cannot do WordArray with: 'aStringValue' neither ByteArray with: 'aStringValue' . What can I do in this case? Do you have any idea?
I mean, I need to use the same parametrer void*, sending it a number or a string.
Declare the method again like
apiSetOption: handle option: anOption string: aString <cdecl: long 'odbx_set_option' (ulong ulong char*) module: 'opendbx' > ^self externalCallFailed
and use that by simply passing a String (don't even bother to convert to ByteArray [but watch out for the terminating 0]).

... that is, unless this works with the original method (I'm not sure):
self apiSetOption: handle option: bla value: 'aStringValue' asByteArray.
