     NAME
          ttyname, isatty - find name of a terminal

     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. Otherwise, it returns 0.

     FILES
          /dev/*

     DIAGNOSTICS
          Ttyname returns a NULL pointer if fildes does not describe a
          terminal device in directory /dev.

     CAVEATS
          The return value points to static data whose content is
          overwritten by each call.  Subdirectories of /dev are not
          handled (e.g., /dev/sxt).
