they get passed the port object, not the port's stream.
* ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
* gc.c (scm_gc_sweep): Pass the port itself to the free function.
* genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
Pass the port itself to the scm_ptobs function.
* ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
scm_generic_fgets): Same.
(putc_void_port, puts_void_port, write_void_port, flush_void_port,
getc_void_port, fgets_void_port, close_void_port): Just change the
argument names; these functions don't really do anything.
* fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
port as an argument, and use SCM_STREAM to get the stdio FILE *.
Also, use prototyped definitions, and get rid of the extra
declarations.
(scm_fptob, scm_pipob): We don't need casts here any more.
* strports.c (prinstpt): Use prototype declarations.
(stputc, stwrite, stputs, stgetc): Take the port as an argument,
and use SCM_STREAM to get the string info. Also, use prototyped
definitions, and get rid of the extra declarations.
* vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
noop0): Same.
Added #include "objects.h"
* eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
Add #include "feature.h".
* ports.h (SCM_EOF_OBJECT_P): New macro predicate.
This test is needed at many places in the code and should be
abstracted. (Motivated by the need of this test in libguiletk.)
* ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
(scm_eval_string), load.c (scm_primitive_load,
scm_read_and_eval_x), gh_eval.c (gh_eval_str):
Use SCM_EOF_OBJECT_P.
* eval.c (scm_init_eval): Add feature `delay'.
eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
vports.c: Cleaned up use of pairs: Don't make any special
assumptions about the internal structure of selectors and
mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
(Among other things, this change makes it easier to build Guile
with certain compilers which have problems with casted lvalues.)
