    TTYNAME(3)	    UNIX Programmer's Manual	       TTYNAME(3)

    NAME
         ttyname, isatty, ttyslot - find name of a terminal

    SYNOPSIS
         char *ttyname(filedes)

         isatty(filedes)

         ttyslot()

    DESCRIPTION
         Ttyname returns a pointer to the null-terminated path name
         of the terminal device associated with file descriptor
         filedes (this is a system file descriptor and has nothing to
         do with the standard I/O FILE typedef).

         Isatty returns 1 if filedes is associated with a terminal
         device, 0 otherwise.

         Ttyslot returns the number of the entry in the ttys(5) file
         for the control terminal of the current process.

    FILES
         /dev/*
         /etc/ttys

    SEE ALSO
         ioctl(2), ttys(5)

    DIAGNOSTICS
         Ttyname returns a null pointer (0) if filedes does not
         describe a terminal device in directory `/dev'.

         Ttyslot returns 0 if `/etc/ttys' is inaccessible or if it
         cannot determine the control terminal.

    BUGS
         The return value points to static data whose content is
         overwritten by each call.
