* 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.

* libc/stdio/fvwrite.c: Change __sfvwrite into reentrant __sfvwrite_r.
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 fputs(const char *<[s]>, FILE *<[fp]>);
|
|
|
|
#include <stdio.h>
|
|
int _fputs_r(struct _reent *<[ptr]>, const char *<[s]>, FILE *<[fp]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <stdio.h>
|
|
int fputs(<[s]>, <[fp]>)
|
|
char *<[s]>;
|
|
FILE *<[fp]>;
|
|
|
|
#include <stdio.h>
|
|
int _fputs_r(<[ptr]>, <[s]>, <[fp]>)

struct _reent *<[ptr]>;
|
|
char *<[s]>;
|
|
FILE *<[fp]>;
|
|
|
|
DESCRIPTION
|
|
<<fputs>> writes the string at <[s]> (but without the trailing null)
|
|
to the file or stream identified by <[fp]>.
|
|
|
|
<<_fputs_r>> is simply the reentrant version of <<fputs>> that takes
|
|
an additional reentrant struct pointer argument: <[ptr]>.
|
|
|
|
RETURNS
|
|
If successful, the result is <<0>>; otherwise, the result is <<EOF>>.
|
|
|
|
PORTABILITY
|
|
ANSI C requires <<fputs>>, but does not specify that the result on
|
|
success must be <<0>>; any non-negative value is permitted.
|
|
|
|
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
|
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
