The data returned by a read(2) on a directory is a set of
complete directory entries ...
`a set'
... by contrast, dirread steps through a directory one
read(2) at a time.
the result of dirread is the result of one read, which might be a set.
... A successful read of a directory always returns an integral number of complete
directory entries; dirread always returns complete Dir structures.
Dirread and dirreadall return the number of Dir structures
filled in buf.
this also suggests the possibility of more than one.
why did you want at most one at a time?
