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. Conforming to SVID 3, POSIX, BSD 4.3 See Also read(2) , closedir(3) , dirfd(3) , opendir(3) , rewinddir(3) , scandir(3) , seekdir(3) , telldir(3)
