unknown type name ‘bit’

Hey Guys
I'm trying to write a function at the moment but it does'nt accept me using a bit.
Probably jsut missing something small.
I get following Error with following function;

CODE:
pos_latch.c:29:5: error: unknown type name ‘bit’
   29 | bit last_Tin;
        | ^~~
make: *** [/usr/share/linuxcnc/Makefile.modinc:117: pos_latch.o] Error 1


FUNCTION:
component pos_latch;
license "GPL";

pin in float Pin;
pin in bit Tin;
pin out float out;

variable bit last_Tin = FALSE;

function _;

;;

FUNCTION(_) {
    if (Tin && !last_Tin) {
        out = Pin;
    }
    last_Tin = Tin;
}

 

Name the file pos_latch.comp, the comp thing makes it go through the preprocessor.

I acctually name it pos_latch.comp when creating the document.


I've created working functions before but those only used floats.
Follwing File installs no problem...:

try:

variable int last_Tin = 0;

I was able to install it now, thank you!
Will update if it works as planed.
