     _\bP_\ba_\bt_\bh is the pathname of a directory.  _\bC_\bh_\bd_\bi_\br causes this
     directory to become the current working directory, the
     starting point for path names not beginning with ``/''.

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

     Upon successful completion, a value of 0 is returned.  Oth-
     erwise, a value of -1 is returned and _\be_\br_\br_\bn_\bo is set to indi-
     cate the error.

     _\bC_\bh_\bd_\bi_\br 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.

     [EINVAL]       The pathname contains a character with the
                    high-order bit set.

     [ENAMETOOLONG] A component of a pathname exceeded 255 char-
                    acters, or an entire path name exceeded 1023
                    characters.

     [ENOENT]       The named directory does not exist.

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

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

     [EFAULT]       _\bP_\ba_\bt_\bh points outside the process's allocated
                    address space.

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