readdir(3) -- Linux man page
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 1003.1-2001 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.
