You hit the nail right on the head... I had the second, but Dumper \@a instead of Dumper $a[0], and my test code was assuming I was returning a list. Hate it when that happens ;-)

OK, so now at least I have it returning something sensible, which is always good. In which case, the question is why does this:

AV * readdir_inode(dirname) char* dirname INIT: struct dirent *ent; DIR* dir; SV* record[2]; AV *entry, *ret_val; CODE: RETVAL = newAV(); dir = opendir(dirname); if (!dir) perror("Cannot open dir"); while ((ent=readdir(dir))) { printf("%ld %x\n", ent->d_ino, ent->d_name); record[0] = newSVpv(ent->d_name, 0); record[1] = newSViv((IV)ent->d_ino); entry = av_make(2, record); av_push(RETVAL, newRV_inc((SV*) entry)); } closedir(dir); /*RETVAL=*ret_val;*/ /*RETVAL=newRV_inc((SV*) ret_val);*/ OUTPUT: RETVAL

Return an extra level of arrays?

The calling code:

my @ents = readdir_inode("."); print Dumper @ents;

The output:

$VAR1 = [ [ '.', 67586 ], [ '..', 255604
