* libc/include/stdio.h: Add new reentrant I/O prototypes for
read/write functions. Change getc/putc macros to have reentrant underlying
macros/functions. This includes __sgetc_raw_r, __sgetc_r, and __sputc_r.
* libc/stdio/fgetc.c: Fix and/or add reentrant version to call
new reentrant I/O functions/macros for reading/writing.
* libc/stdio/fgets.c: Ditto.
* libc/stdio/fputc.c: Ditto.

Change all previous callers of __sfvwrite. Set errno to EBADF and
set error flag on if attempt is made to write to file that does not
allow writing.
* libc/stdio/fvwrite.h: Fix new reentrant prototypes.
* libc/stdio/local.h: Ditto.
* libc/stdio/refill.c: Turn __srefill into reentrant __srefill_r.
Set errno to EBADF and the error flag on if attempt is made to
read unreadable file. Change all previous callers of __srefill.
* libc/stdio/rget.c
* libc/stdio/wbuf.c: Turn __swbuf into reentrant __swbuf_r. Change
all previous callers of __swbuf.
* libc/sys/linux/machine/i386/huge_val.h: Ifdef out file contents since
huge value macros are already defined correctly for i386 by <math.h>.

ANSI_SYNOPSIS
|
|
#include <stdio.h>
|
|
int fputc(int <[ch]>, FILE *<[fp]>);
|
|
|
|
#include <stdio.h>
|
|
int _fputc_r(struct _rent *<[ptr]>, int <[ch]>, FILE *<[fp]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <stdio.h>
|
|
int fputc(<[ch]>, <[fp]>)
|
|
int <[ch]>;
|
|
FILE *<[fp]>;
|
|
|
|
#include <stdio.h>
|
|
int _fputc_r(<[ptr]>, <[ch]>, <[fp]>)
|
|
struct _reent *<[ptr]>;
|
|
int <[ch]>;
|
|
FILE *<[fp]>;
|
|
|
|
DESCRIPTION
|
|
<<fputc>> converts the argument <[ch]> from an <<int>> to an
|
|
<<unsigned char>>, then writes it to the file or stream identified by
|
|
<[fp]>.
|
|
|
|
If the file was opened with append mode (or if the stream cannot
|
|
support positioning), then the new character goes at the end of the
|
|
file or stream. Otherwise, the new character is written at the
|
|
current value of the position indicator, and the position indicator
|
|
oadvances by one.
|
|
|
|
For a macro version of this function, see <<putc>>.
|
|
|
|
The <<_fputc_r>> function is simply a reentrant version of <<fputc>>
|
|
that takes an additional reentrant structure argument: <[ptr]>.
|
|
|
|
RETURNS
|
|
If successful, <<fputc>> returns its argument <[ch]>. If an error
|
|
intervenes, the result is <<EOF>>. You can use `<<ferror(<[fp]>)>>' to
|
|
query for errors.
|
|
|
|
PORTABILITY
|
|
<<fputc>> is required by ANSI C.
|
|
|
|
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
|
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
