Need to convert Perl unpack to Inline::C AV*

I am struggling a bit to convert a Perl unpack to Inline::C

@array = unpack("C*", $buf);

This is what I have so far, but I am an Inline::C novice so I am having trouble of what to do next:

STRLEN len;
char* test = SvPVbyte(buf, len);
...
AV* arr = SvRV(?);

Can anyone provide a tip to how to do this?

The smart thing here is probably to avoid calling unpack, and do what unpack would do, which is simpler.

STRLEN len;
char *str = SvPVbyte(buf, len);
AV *arr = newAV();
char *ptr;

for (ptr = str; ptr < str + len ; ptr++) {
    SV *char_value = newSViv(*ptr);
    av_push(arr, char_value);
}

Or, of course, just write the loop and leave out the array if you don't need it :)
