readdir
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. CONFORMING TO
