Log message:
Major API changes of the standard IO facilities.
Part of these changes (passing user data to get and put) have been
contributed by Ted Roth as patch #3750.
* include/stdio.h: implement the new prototype for fdevopen() that
allows passing user data to the backend put and get functions;
retain a backwards-compatible prototype iff
__STDIO_FDEVOPEN_COMPAT_12 is defined before including stdio.h; move
definition of struct __file from stdio_internal.h here, so user code
will be able to directly declare objects of type FILE; include the
udata field in struct __file; add macros fdev_set_udata() and
fdev_get_udata() to access the user data field; implement a
macro-based, malloc()-free alternative API to fdevopen() consisting
of the macros fdev_setup_stream() and FDEV_SETUP_STREAM() together
with _FDEV_SETUP_READ, _FDEV_SETUP_WRITE, and _FDEV_SETUP_RW that
can be passed to declare the open intent; add _FDEV_ERR and
_FDEV_EOF to be returned by the internal get function; add inline
macros shadowing the functions clearerr(), feof(), and ferror() (now
that struct __file is user-visible); add documentation for all the
API changes in the introduction; sub-structure the introductional
doxygen comment; remove the "this is likely to be changed in future"
warning.
* libc/stdio/fdevopen.c (fdevopen): Update dox for new get and put
argument types. Change the get() and put() function pointers so
that they take the stream as an argument. Remove the definition of
__iob[] to avoid the need for dragging in fdevopen() to access the
standard streams.
* libc/stdio/fgetc.c (fgetc): Pass stream to get() method; set __SERR
or __SEOF dependent of the backend's return code.
* libc/stdio/fputc.c (fputc): Pass stream to put() method.
* libc/stdio/fputs.c (fputs): Ditto.
* libc/stdio/fputs_p.c (fputs_P): Ditto.
* libc/stdio/fwrite.c (fwrite): Ditto.
* libc/stdio/puts.c (puts): Ditto.
* libc/stdio/puts_p.c (puts_P): Ditto.
* libc/stdio/stdio_private.h: remove struct __file from here.
* libc/stdio/iob.c: New file (split off of fdevopen.c).
* libc/stdio/Files.am: add iob.c.
* doc/examples/twitest/twitest.c: convert to the new stdio API.
* libc/stdio/clearerr.c: undef the shadow macro first.
* libc/stdio/ferror.c: (Ditto.)
* libc/stdio/feof.c: (Ditto.)
* libc/stdio/fclose.c: change inttypes.h into stdint.h.
* libc/stdio/fgets.c: don't forcibly set __SERR, getc() already
handled that.
* libc/stdio/gets.c: (Ditto.)
* libc/stdio/vfprintf.c: Allocate the fp conversion buffer on
the stack as opposed to using malloc().
* libc/stdio/vfscanf.c: (Ditto.)
