CHDIR(2)		  FreeBSD System Calls Manual		      CHDIR(2)

NAME
     chdir, fchdir -- change current working directory

SYNOPSIS
     #include <unistd.h>

     int
     chdir(const char *path);

     int
     fchdir(int	fd);

DESCRIPTION
     The path argument points to the pathname of a directory.  The chdir()
     function causes the named directory to become the current working direc-
     tory, that	is, the	starting point for path	searches of pathnames not be-
     ginning with a slash (`/').

     The fchdir() function causes the directory	referenced by fd to become the
     current working directory,	the starting point for path searches of	path-
     names not beginning with a	slash (`/').

     In	order for a directory to become	the current directory, a process must
     have execute (search) access to the directory.

RETURN VALUES
     Upon successful completion, the value 0 is	returned; otherwise the
     value -1 is returned and the global variable errno	is set to indicate the
     error.

ERRORS
     chdir() will fail and the current working directory will be unchanged if
     one or more of the	following are true:

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

     [ENAMETOOLONG]	A component of a pathname exceeded NAME_MAX charac-
			ters, or an entire pathname (including the terminating
			NUL) exceeded PATH_MAX bytes.

     [ENOENT]		The named directory does not exist.

     [ELOOP]		Too many symbolic links	were encountered in translat-
			ing the	pathname.

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

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

     [EIO]		An I/O error occurred while reading from the file sys-
			tem.

     fchdir() will fail	and the	current	working	directory will be unchanged if
     one or more of the	following are true:

     [EACCES]		Search permission is denied for	the directory refer-
			enced by the file descriptor.

     [ENOTDIR]		The file descriptor does not reference a directory.

     [EBADF]		The argument fd	is not a valid file descriptor.

     [EIO]		An I/O error occurred while reading from the file sys-
			tem.

STANDARDS
     The chdir() and fchdir() functions	are expected to	conform	to IEEE	Std
     1003.1-2008 ("POSIX.1").

HISTORY
     The chdir() system	call first appeared in Version 1 AT&T UNIX, and
     fchdir() in 4.3BSD-Reno.
