SYNOPSIS
     char *ttyname (fildes)
     int fildes;

     int isatty (fildes)
     int fildes;

DESCRIPTION
     ttyname returns a pointer to a string containing the null-
     terminated path name of the terminal device associated with
     file descriptor fildes.

     isatty returns 1 if fildes is associated with a terminal
     device, 0 otherwise.

DIAGNOSTICS
     ttyname returns a NULL pointer if fildes does not describe a

     cannot be determined.

     overwritten by each call.
