readdir(3) |

readdir − read a directory
#include <sys/types.h>
#include <dirent.h>
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-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.
