If this is Sun's cp, file a bug. It's failing to notice that it didn't
provide a large enough buffer to getdents(), so it only got partial results.
Of course, the getdents() API is rather unfortunate. It appears the only
safe algorithm is:
while ((r = getdents(...)) > 0) {
/* process results */
}
if (r < 0) {
/* handle error */
}
You _always_ have to call it at least twice to be sure you've gotten
everything.
