Most importantly, I am looking for a way to get the $0 value of a patch from C.
In all cases, you need to get a canvas environment (there is one per file
loaded, that is, one per distinct value of $0) :
t_canvasenvironment *e = canvas_getenv(x->parent);
but you need to have a variable in your struct for accessing your parent :
t_canvas *parent;
that you need to set in the creator (constructor) because that's the only
time you can obtain that information :
x->parent = canvas_getcurrent();
but when you need to get the $0, you need the e and you use this :
e->ce_dollarzero
and if you need to get $1, $2, $3, ... you use these :
e->ce_argv[0] /* $1 */
e->ce_argv[1] /* $2 */
e->ce_argv[2] /* $3 */
...
but you don't use indices that are >= e->ce_argc, which is the number of
arguments.
