name for a Scheme object (now a void*), and SCM as 32 bit word for
storing tags and immediates (now a long int). Introduced
SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
code in the process: arbiter.c (use macros), unif.c (scm_array_p),
net_db.c, read.c, socket.c: Update error messages to use ~A for
%s, ~S for %S to work with new `simple-format' format and be
standardized better.
* print.h, print.c (scm_simple_format): Added `simple-format'
primitive. It's the old scm_display_error, with ARGS now a rest
parameter, and the destination first instead of last (and a couple
new capabilities inspired by `format' -- #t as destination means
current-output-port, #f means return the formatted text as a
string.
* gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
* backtrace.c (scm_display_error_message): Rewrote to use
scm_simple_format() procedure.

* strports.c (st_flush, st_end_input): Same.
* fports.c (fport_input_waiting): if select is used, return 1

lower bound on the number of bytes available.

second argument instead of the flush procedure.

creation of port types (replaces scm_newptob). Just as for the
smobs, we need to separate the internal representation of smob
types from the interface, so that we easily can add new fields and
rearrange things without caring about backward compatibility.
This change was forced by the need in GOOPS to create classes
representing port types.

Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
waiting for input caused an EINTR error from read.

use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
* readline.c (scm_readline): Applied a patch from Greg Harvey to
get readline support working again: use fdopen to get FILE objects.
* gc.c (scm_init_storage): install an atexit proc to flush the
ports.
(cleanup): the new proc. it sets a global variable which can be
checked by the ptob flush procs to avoid trying to throw
exceptions during exit. not very pleasant but it seems more reliable.

don't throw exception.
* CHECKME: that the atexit proc is installed if unexec used.

currently use shortbuf.)
* fports.c (scm_standard_stream_to_port): moved to init.c and
made static.
* init.c (scm_init_standard_ports): make stdout and stderr
unbuffered if connected to a terminal. with stdio they
were line-buffered by default.

buffer instead of port stream.

* ports.h (struct scm_port_table): added write_end member,
as an optimisation. set it where write_buf_size is set.

back to SCM. SCM presumably must be large enough to hold a
pointer (and probably vice versa but who knows.)

replaces reading member in fport struct.
* vports.c (sfgetc): store the getted char into the buffer.
rename to sf_fill_buffer and install it for fill-buffer in ptob.
the Scheme interface is still a procedure that gets a char.
(scm_make_soft_port): set up the port buffer (shortbuf).

* fports.h (SCM_FDES_RANDOM_P): new macro. use it in
scm_fdes_to_port and scm_redirect_port.

(local_fflush): flush fdes, not FILE *.
* fports.h (SCM_NOFTELL): removed.
* genio.c, ports.c: don't include filesys.h.
