READDIR(3)						     Linux Programmer's Manual							READDIR(3)

NAME

       readdir - read a directory

SYNOPSIS

       #include <sys/types.h>

       #include <dirent.h>

       struct dirent *readdir(DIR *dir);

DESCRIPTION

       The  readdir() function returns a pointer to a dirent structure representing the next directory entry in the directory stream pointed to by
       dir.  It returns NULL on reaching the end-of-file or if an error occurred.

       According to POSIX, the dirent structure contains a field char d_name[] of unspecified size, with at most NAME_MAX characters preceding the
       terminating  null  character.   Use  of other fields will harm the portability of your programs.  POSIX-2001 also documents the field ino_t
       d_ino as an XSI extension.

       The data returned by readdir() may be overwritten by subsequent calls to readdir() for the same directory stream.

RETURN VALUE

       The readdir() function returns a pointer to a dirent structure, or NULL if an error occurs or end-of-file is reached.

ERRORS

       EBADF  Invalid directory stream descriptor dir.
