The \fIpath\fR argument points to the path name of a directory. The \fIfildes\fR argument is an open file descriptor of a directory. .sp .LP For a directory to become the current directory, a process must have execute (search) access to the directory. .SH RETURN VALUES .sp .LP Upon successful completion, \fB0\fR is returned.
