ctermid — get controlling terminal name
#include <stdio.h>

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.
The path returned 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.
