NAME
	  chdir, fchdir	-  Changes the current directory

     SYNOPSIS
	  int chdir (
	       const char *path	);
	  int fchdir (
	       int filedes );



     PARAMETERS
	  path	    Points to the pathname of the directory.

	  filedes   Specifies the file descriptor of the directory.


     DESCRIPTION
	  The chdir() function changes the current directory to	the
	  directory indicated by the path parameter.

	  The fchdir() function	changes	the current directory to the
	  directory indicated by the filedes parameter.	 If the	path
	  parameter refers to a	symbolic link, the chdir() function
	  sets the current directory to	the directory pointed to by
	  the symbolic link.

	  The current directory, also called the current working
	  directory, is	the starting point of searches for pathnames
	  that do not begin with a / (slash).	In order for a direc-
	  tory to become the current directory,	the calling process
	  must have search access to the directory.

     NOTES
	  The current working directory	is shared between all threads
	  within the same process.  Therefore, one thread using	the
	  chdir() or fchdir() functions	will affect every other	thread
	  in that process.


	  AES Support Level:
			 Full use chdir() only


     RETURN VALUES
	  Upon successful completion, the chdir() function returns a
	  value	of 0 (zero).  Otherwise, a value of -1 is returned and
	  errno	is set to indicate the error.

     ERRORS
	  If the chdir() function fails, the current directory remains
	  unchanged and	errno may be set to one	of the following
	  values:


	  [EACCES]  Search access is denied for	any component of the
		    pathname.

	  [ELOOP]   Too	many symbolic links were encountered in
		    translating	the pathname.

	  [EFAULT]  The	path parameter points outside the process's
		    allocated address space.

	  [EIO]	    An I/O error occurred while	reading	from or	writ-
		    ing	to the file system.

	  [ENOENT]  The	named directory	does not exist,	or is an empty
		    string.

	  [ENOTDIR] A component	of the path prefix is not a directory.

	  [ENAMETOOLONG]
		    The	length of the path argument exceeds PATH_MAX
		    or a pathname component is longer than NAME_MAX
		    while [_POSIX_NO_TRUNC} is in effect.


	  If the fchdir() function fails, the current directory
	  remains unchanged and	errno may be set to one	of the follow-
	  ing values:


	  [EACCESS] The	search permission is denied for	the directory
		    referenced by the file descriptor.

	  [ENOTDIR] The	file descriptor	does not reference a direc-
		    tory.

	  [EBADF]   The	filedes	parameter is not a valid open file
		    descriptor.
