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.

       The  data  returned  by  readdir() is overwritten by subsequent calls to readdir() for the same directory
       stream.

       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.

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.
