DESCRIPTION
ctermid() returns a string
which is the pathname for the current controlling terminal
for this process. If s is NULL, a static buffer is
used, otherwise s
points to a buffer used to hold the terminal pathname. The
symbolic constant L_ctermid is
the maximum number of characters in the returned
pathname.

BUGS
The returned pathname may not uniquely identify the
controlling terminal; it may, for example, be /dev/tty.
It is not assured that the program can open the terminal.
