set_break, clear_break, start_output, set_bits (which now takes an
struct termios * as argument), mdmctl and mdmstate (which now
takes an int * as argument). Add new members init and type.
(bottom): Define as const.
(devio_bottom, ptyio_bottom): Declare as const.
(drop_output): Change return type from void to error_t.
(ptyio_init): Remove prototype.

than bailing out. Declare as static.

devio_init.
(devio_set_bits): Accept new argument STATE and use that to work
out the terminal state, rather than changing the global termstate.

the bits.
* ptyio.c: Do not include `hurd/hurd_types.h'.

clear queue if there was no error.
* users.c (S_term_get_bottom_type): Just return bottom->type.
(set_state): Rework logic to take possible errors into account,
and to delay changing the termstate until we know that we won't
fail.
(S_tioctl_tiocflush): Return errors properly, and clear queue only
if notice_input_flushed succeeded.
(open_hook): Save error value of set_bits. Save old termflags and
restore them if if set_bits failed. Call set_bits with correct
arguments.

* devio.c (bogus_speed_to_real_speed): Handle B57600, B115200 if
they are defined. Reported by Diego Roversi <diegor@tiscalinet.it>.
|
|
|
|
* munge.c (input_character): Fix DISCARD character handling
so it doesn't process the character as plain input.
|
|
|
|
* devio.c (real_speed_to_bogus_speed): Handle B57600, B115200 if they
are defined. Reported by Diego Roversi <diegor@tiscalinet.it>.

|
|
|
|
* users.c (trivfs_S_io_select): Mask out SELECT_READ and/or
SELECT_WRITE if those accesses are not allowed by the peropen.
Don't keep old bits in AVAILABLE across waits, return only
what is true at the moment we return.
|
|
|
|
* users.c (trivfs_S_io_select): Don't diagnose an error for *TYPE
containing irrelevant bits (i.e. SELECT_URG). It's always ok to
ask even when the answer is always no.
