passing hex value to an external.bundle

[Thierry]

Hi,

I'm coding a C++ external with:

MacOS Mojave, LC 9.6.0, Xcode 11.3.1


Passing hex value to a function() of the external ( .bundle),
0x0A is transformed to 0,
0x0B to 1,
0x3E to 48,...

in LC:

get test( 0x09, 0x0A, 0x0B )

in lcidl:
function test
in v0 as integer
in v1 as integer
in v2 as integer
return boolean

in Xcode:

So, I get a wrong value at fetch_int(...).


get test( 10, 11, 12) // works as expected.


Any thoughts?

I did something in the past with sending HEX to a Touchscreen, which worked OK.
I don't have it with me right now. But i can post it later.

Anyway, can you clearify what your are actaully asking? Because only the question "any thoughts?" does not ring a bell. I have many thoughts during the day.
So let us know what you exactly mean

I did too and I was used to get right values.

Sorry, if this was not clear; I guess the word 'external' was too wild...

In the OP context, it's all about passing hex value to a C++ external,
using the lcidlc compiler.
fetch_int() is a function from LiveCode, and it doesn't give the right value;
nothing more to say really, as long as one know how to build an external...

and the screenshots show clearly the problem I'm facing.

Hi Thierry,

maybe you can also post to

e.g. Monte, Trevor, and Paul McClernan visit Gitter regularly.
