The 'expanded' program ... main():
int main() {
/* local addresses */
test("fe80::221:5eff:fea3:c746%0");
test("fe80::221:5eff:fea3:c746%en0");
test("fe80::f8d1:8cff:fe32:8305%2");
test("fe80::f8d1:8cff:fe32:8305%en1");
/* remote addresses */
test("fe80::f8d1:81ff:fe81:ac05%2");
test("fe80::f8d1:81ff:fe81:ac05%en1");
return 0;
}
The conclusion seems to be that the scopeid returned is always 0 - when
it is working;
The status is always "8", when it fails.
This seems to be:
#define EAI_NONAME 8 /* hostname nor servname not provided,
or not known */
So, %enX is not recognized - only a numerical scope.

On the first server - added two addresses - they are local to platform.

*** In closing ***
Maybe AIX needs "hints" to reveal the scopeid. There is a lot of 'talk'
about that
in the man page. I can attach that in a new email if you do not have that.
