readdir - read a directory
Návod, kniha: Linux Programmer's Manual

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