/* ctermid(3)
*
* Author: Terrence Holm Aug. 1988
*
*
* Ctermid(3) returns a pointer to a string naming the controlling
* terminal. If <name_space> is NULL then local PRIVATE storage
* is used, otherwise <name_space> must point to storage of at
* least L_ctermid characters.
*
* Returns a pointer to "/dev/tty".
