WARNINGS

readdir() and getdirentries()

(see getdirentries(2)) are the only ways to access remote NFS

directories. Attempting to read a remote directory via NFS by using

read() returns -1 and sets errno

to [EISDIR] (see read(2)).

If a ﬁle is removed from or added to the directory after the most recent call to

opendir() or rewind-

dir()

, whether a subsequent call to readdir()

or readdir_r() returns an entry for that ﬁle is

unspeciﬁed.

For 32-bit applications, the d_ino ﬁeld of the

dirent struct may overﬂow for ﬁlesystems that use 64-bit

values. In this case the most-signiﬁcant bytes will be truncated without generating an error and d_ino

values may not be unique.
