Hello

Is it possible to GRASS Scripts to call external functions? I mean compiled C functions that has nothing to do with GRASS API?

Merci & Thank you

Yes. How exactly you call them will depend on what language you write your
script in. It probably doesn't hurt to have the program be in your system
$PATH.

Good Evening

So for instance if I create an hello world function, in C, can I just call it from a Bash Script? as long as it is on my $PATH?

(yes) You can call the binary, i.e. creating the "hello world" binary from
the source code by compiling it first. Then you can call it.
