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.

APPLICATION USAGE

The header ﬁle required for these functions and the type of the return value from

readdir() has been

changed for compatibility with System V Release 3 and the X/Open Portability Guide. See ndir(5) for a

description of the header ﬁle

<ndir.h>, which is provided to allow existing HP-UX applications to com-

pile unmodiﬁed. <ndir.h> header ﬁle is obsoleted starting from HP-UX 10.30 and is available in

/usr/old/usr/include

directory.

New applications should use the

<dirent.h> header ﬁle for portability to System V and X/Open systems.

The <ndir.h> header ﬁle is obsoleted starting from HP-UX 10.30 and is going to be removed in future

releases.

Users of readdir_r() should note that readdir_r() now conforms with the POSIX.1c Threads stan-

dard. The old prototype of readdir_r() is supported for compatibility with existing DCE applications

only.
