       getdents - get directory entries

       #include <unistd.h>
       #include <linux/types.h>
       #include <linux/dirent.h>
       #include <linux/unistd.h>

       _syscall3(int, getdents, uint, fd, struct dirent *, dirp, uint, count);

       int getdents(unsigned int fd, struct dirent *dirp, unsigned int count);

       getdents reads several dirent structures from the directory pointed at by fd into the mem-
       ory area pointed to by dirp.  The parameter count is the size of the memory area.

       The dirent structure is declared as follows:

	      struct dirent
		  long d_ino;		      /* inode number */
		  off_t d_off;		      /* offset to next dirent */
		  unsigned short d_reclen;    /* length of this dirent */
		  char d_name [NAME_MAX+1];   /* file name (null-terminated) */

       d_ino is an inode number.  d_off is the distance from the start of the  directory  to  the
       start  of the next dirent.  d_reclen is the size of this entire dirent.	d_name is a null-
       terminated file name.

       This call supersedes readdir(2).

       On success, the number of bytes read is returned.  On end of directory, 0 is returned.  On
       error, -1 is returned, and errno is set appropriately.

       EBADF  Invalid file descriptor fd.

       EFAULT Argument points outside the calling process's address space.

       EINVAL Result buffer is too small.

       ENOENT No such directory.

	      File descriptor does not refer to a directory.

       SVr4, SVID.  SVr4 documents additional ENOLINK, EIO error conditions.

       readdir(2), readdir(3)
