emacs_tty should contain an element for each parameter struct
that Emacs may change.
- EMACS_GET_TTY (int FD, struct emacs_tty *P) stores the
- parameters of the tty on FD in *P.
+ EMACS_GET_TTY (int FD, struct emacs_tty *P) stores the parameters
+ of the tty on FD in *P. Return zero if all's well, or -1 if we ran
+ into an error we couldn't deal with.
- EMACS_SET_TTY (int FD, struct emacs_tty *P, int waitp)
+ EMACS_SET_TTY (int FD, struct emacs_tty *P, int flushp)
sets the parameters of the tty on FD according to the contents of
- *P. If waitp is non-zero, we wait for all queued output to be
- written before making the change; otherwise, we forget any queued
- input and make the change immediately.
+ *P. If flushp is non-zero, we discard queued input to be
+ written before making the change.
+ Return 0 if all went well, and -1 if anything failed.
EMACS_TTY_TABS_OK (struct emacs_tty *P) is false iff the kernel
expands tabs to spaces upon output; in that case, there is no
advantage to using tabs over spaces. */
