getdents(2)                      System Calls                      getdents(2)



NAME
       getdents  - read directory entries and put in a file system independent
       format

SYNOPSIS
       #include <dirent.h>

       int getdents(int fildes, struct dirent *buf, size_t nbyte);

DESCRIPTION
       The getdents() function attempts to read nbyte bytes from the directory
       associated  with  the file descriptor fildes and to format them as file
       system independent directory entries in the buffer pointed to  by  buf.
       Since  the  file  system  independent directory entries are of variable
       lengths, in most cases the actual number of bytes returned will be less
       than nbyte. The file system independent directory entry is specified by
       the dirent structure. See dirent.h(3HEAD).


       On devices capable of seeking, getdents() starts at a position  in  the
       file given by the file pointer associated with fildes. Upon return from
       getdents(), the file pointer is incremented to point to the next direc‐
       tory entry.

RETURN VALUES
       Upon successful completion, a non-negative integer is returned indicat‐
       ing the number of bytes actually read. A return value  of  0  indicates
       the  end  of  the directory has been reached. Otherwise, −1 is returned
       and errno is set to indicate the error.

ERRORS
       The getdents() function will fail if:

       EBADF        The fildes argument is not a valid  file  descriptor  open
                    for reading.


       EFAULT       The buf argument points to an illegal address.


       EINVAL       The  nbyte  argument is not large enough for one directory
                    entry.


       EIO          An I/O error occurred while accessing the file system.


       ENOENT       The current file pointer for the directory is not  located
                    at a valid entry.


       ENOLINK      The  fildes  argument  points  to a remote machine and the
                    link to that machine is no longer active.


       ENOTDIR      The fildes argument is not a directory.


       EOVERFLOW    The value of the dirent structure member  d_ino  or  d_off
                    cannot be represented in an ino_t or off_t.


USAGE
       The  getdents()  function  was  developed  to implement the readdir(3C)
       function and should not be used for other purposes.


       The getdents() function has a transitional interface  for  64-bit  file
       offsets. See lf64(7).
