INDEX
_fcloseall_r
ANSI_SYNOPSIS
#include <stdio.h>
int fcloseall(void);
int _fcloseall_r (struct _reent *<[ptr]>);
TRAD_SYNOPSIS
#include <stdio.h>
int fcloseall()
int _fcloseall_r (<[ptr]>)
struct _reent *<[ptr]>;
DESCRIPTION
<<fcloseall>> closes all files in the current reentrancy struct's domain.
The function <<_fcloseall_r>> is the same function, except the reentrancy
struct is passed in as the <[ptr]> argument.
This function is not recommended as it closes all streams, including
the std streams.
RETURNS
<<fclose>> returns <<0>> if all closes are successful. Otherwise,
EOF is returned.
PORTABILITY
<<fcloseall>> is a glibc extension.
Required OS subroutines: <<close>>, <<fstat>>, <<isatty>>, <<lseek>>,
<<read>>, <<sbrk>>, <<write>>.

FUNCTION
<<fgetpos>>---record position in a stream or file
INDEX
fgetpos
INDEX
_fgetpos_r
ANSI_SYNOPSIS
#include <stdio.h>
int fgetpos(FILE *restrict <[fp]>, fpos_t *restrict <[pos]>);
int _fgetpos_r(struct _reent *<[ptr]>, FILE *restrict <[fp]>, fpos_t *restrict <[pos]>);
TRAD_SYNOPSIS
#include <stdio.h>
int fgetpos(<[fp]>, <[pos]>)
FILE *<[fp]>;
fpos_t *<[pos]>;
int _fgetpos_r(<[ptr]>, <[fp]>, <[pos]>)
struct _reent *<[ptr]>;
FILE *<[fp]>;
fpos_t *<[pos]>;
DESCRIPTION
Objects of type <<FILE>> can have a ``position'' that records how much
of the file your program has already read. Many of the <<stdio>> functions
depend on this position, and many change it as a side effect.
You can use <<fgetpos>> to report on the current position for a file
identified by <[fp]>; <<fgetpos>> will write a value
representing that position at <<*<[pos]>>>. Later, you can
use this value with <<fsetpos>> to return the file to this
position.
In the current implementation, <<fgetpos>> simply uses a character
count to represent the file position; this is the same number that
would be returned by <<ftell>>.
RETURNS
<<fgetpos>> returns <<0>> when successful. If <<fgetpos>> fails, the
result is <<1>>. Failure occurs on streams that do not support
positioning; the global <<errno>> indicates this condition with the
value <<ESPIPE>>.
PORTABILITY
<<fgetpos>> is required by the ANSI C standard, but the meaning of the
value it records is not specified beyond requiring that it be
acceptable as an argument to <<fsetpos>>. In particular, other
conforming C implementations may return a different result from
<<ftell>> than what <<fgetpos>> writes at <<*<[pos]>>>.
No supporting OS subroutines are required.

FUNCTION
<<fmemopen>>---open a stream around a fixed-length string
INDEX
fmemopen
ANSI_SYNOPSIS
#include <stdio.h>
FILE *fmemopen(void *restrict <[buf]>, size_t <[size]>,
const char *restrict <[mode]>);
DESCRIPTION
<<fmemopen>> creates a seekable <<FILE>> stream that wraps a
fixed-length buffer of <[size]> bytes starting at <[buf]>. The stream
is opened with <[mode]> treated as in <<fopen>>, where append mode
starts writing at the first NUL byte. If <[buf]> is NULL, then
<[size]> bytes are automatically provided as if by <<malloc>>, with
the initial size of 0, and <[mode]> must contain <<+>> so that data
can be read after it is written.
The stream maintains a current position, which moves according to
bytes read or written, and which can be one past the end of the array.
The stream also maintains a current file size, which is never greater
than <[size]>. If <[mode]> starts with <<r>>, the position starts at
<<0>>, and file size starts at <[size]> if <[buf]> was provided. If
<[mode]> starts with <<w>>, the position and file size start at <<0>>,
and if <[buf]> was provided, the first byte is set to NUL. If
<[mode]> starts with <<a>>, the position and file size start at the
location of the first NUL byte, or else <[size]> if <[buf]> was
provided.
When reading, NUL bytes have no significance, and reads cannot exceed
the current file size. When writing, the file size can increase up to
<[size]> as needed, and NUL bytes may be embedded in the stream (see
<<open_memstream>> for an alternative that automatically enlarges the
buffer). When the stream is flushed or closed after a write that
changed the file size, a NUL byte is written at the current position
if there is still room; if the stream is not also open for reading, a
NUL byte is additionally written at the last byte of <[buf]> when the
stream has exceeded <[size]>, so that a write-only <[buf]> is always
NUL-terminated when the stream is flushed or closed (and the initial
<[size]> should take this into account). It is not possible to seek
outside the bounds of <[size]>. A NUL byte written during a flush is
restored to its previous value when seeking elsewhere in the string.
RETURNS
The return value is an open FILE pointer on success. On error,
<<NULL>> is returned, and <<errno>> will be set to EINVAL if <[size]>
is zero or <[mode]> is invalid, ENOMEM if <[buf]> was NULL and memory
could not be allocated, or EMFILE if too many streams are already
open.
PORTABILITY
This function is being added to POSIX 200x, but is not in POSIX 2001.
Supporting OS subroutines required: <<sbrk>>.

FUNCTION
<<fopencookie>>---open a stream with custom callbacks
INDEX
fopencookie
ANSI_SYNOPSIS
#include <stdio.h>
FILE *fopencookie(const void *<[cookie]>, const char *<[mode]>,
cookie_io_functions_t <[functions]>);
DESCRIPTION
<<fopencookie>> creates a <<FILE>> stream where I/O is performed using
custom callbacks. The callbacks are registered via the structure:
typedef ssize_t (*cookie_read_function_t)(void *_cookie, char *_buf,
size_t _n);
typedef ssize_t (*cookie_write_function_t)(void *_cookie,
const char *_buf, size_t _n);
typedef int (*cookie_seek_function_t)(void *_cookie, off_t *_off,
int _whence);
typedef int (*cookie_close_function_t)(void *_cookie);
. typedef struct
. {
. cookie_read_function_t *read;
. cookie_write_function_t *write;
. cookie_seek_function_t *seek;
. cookie_close_function_t *close;
. } cookie_io_functions_t;
The stream is opened with <[mode]> treated as in <<fopen>>. The
callbacks <[functions.read]> and <[functions.write]> may only be NULL
when <[mode]> does not require them.
<[functions.read]> should return -1 on failure, or else the number of
bytes read (0 on EOF). It is similar to <<read>>, except that
<[cookie]> will be passed as the first argument.
<[functions.write]> should return -1 on failure, or else the number of
bytes written. It is similar to <<write>>, except that <[cookie]>
will be passed as the first argument.
<[functions.seek]> should return -1 on failure, and 0 on success, with
*<[_off]> set to the current file position. It is a cross between
<<lseek>> and <<fseek>>, with the <[_whence]> argument interpreted in
the same manner. A NULL <[functions.seek]> makes the stream behave
similarly to a pipe in relation to stdio functions that require
positioning.
<[functions.close]> should return -1 on failure, or 0 on success. It
is similar to <<close>>, except that <[cookie]> will be passed as the
first argument. A NULL <[functions.close]> merely flushes all data
then lets <<fclose>> succeed. A failed close will still invalidate
the stream.
Read and write I/O functions are allowed to change the underlying
buffer on fully buffered or line buffered streams by calling
<<setvbuf>>. They are also not required to completely fill or empty
the buffer. They are not, however, allowed to change streams from
unbuffered to buffered or to change the state of the line buffering
flag. They must also be prepared to have read or write calls occur on
buffers other than the one most recently specified.
RETURNS
The return value is an open FILE pointer on success. On error,
<<NULL>> is returned, and <<errno>> will be set to EINVAL if a
function pointer is missing or <[mode]> is invalid, ENOMEM if the
stream cannot be created, or EMFILE if too many streams are already
open.
PORTABILITY
This function is a newlib extension, copying the prototype from Linux.
It is not portable. See also the <<funopen>> interface from BSD.
Supporting OS subroutines required: <<sbrk>>.

FUNCTION
<<fpurge>>---discard pending file I/O

_fpurge_r
INDEX
__fpurge
ANSI_SYNOPSIS
#include <stdio.h>
int fpurge(FILE *<[fp]>);
int _fpurge_r(struct _reent *<[reent]>, FILE *<[fp]>);
#include <stdio.h>
#include <stdio_ext.h>
void __fpurge(FILE *<[fp]>);
DESCRIPTION
Use <<fpurge>> to clear all buffers of the given stream. For output
streams, this discards data not yet written to disk. For input streams,
this discards any data from <<ungetc>> and any data retrieved from disk
but not yet read via <<getc>>. This is more severe than <<fflush>>,
and generally is only needed when manually altering the underlying file
descriptor of a stream.
<<__fpurge>> behaves exactly like <<fpurge>> but does not return a value.
The alternate function <<_fpurge_r>> is a reentrant version, where the
extra argument <[reent]> is a pointer to a reentrancy structure, and
<[fp]> must not be NULL.
RETURNS
<<fpurge>> returns <<0>> unless <[fp]> is not valid, in which case it
returns <<EOF>> and sets <<errno>>.
PORTABILITY
These functions are not portable to any standard.
No supporting OS subroutines are required.

<<FSETLOCKING_INTERNAL>> is the default state, where stdio functions
automatically lock and unlock the stream.
<<FSETLOCKING_BYCALLER>> means that automatic locking in stdio functions

DESCRIPTION
Objects of type <<FILE>> can have a ``position'' that records how much
of the file your program has already read. Many of the <<stdio>> functions
depend on this position, and many change it as a side effect.
You can use <<fsetpos>> to return the file identified by <[fp]> to a previous
position <<*<[pos]>>> (after first recording it with <<fgetpos>>).
See <<fseek>> for a similar facility.
RETURNS
<<fgetpos>> returns <<0>> when successful. If <<fgetpos>> fails, the
result is <<1>>. The reason for failure is indicated in <<errno>>:
either <<ESPIPE>> (the stream identified by <[fp]> doesn't support
repositioning) or <<EINVAL>> (invalid file position).
PORTABILITY
ANSI C requires <<fsetpos>>, but does not specify the nature of
<<*<[pos]>>> beyond identifying it as written by <<fgetpos>>.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

DESCRIPTION
<<funopen>> creates a <<FILE>> stream where I/O is performed using

as the first argument. A NULL <[readfn]> makes attempts to read the

<[writefn]> should return -1 on failure, or else the number of bytes
written. It is similar to <<write>>, except that <int> rather than
<size_t> bounds a transaction size, and <[cookie]> will be passed as
the first argument. A NULL <[writefn]> makes attempts to write the
stream fail.
<[seekfn]> should return (fpos_t)-1 on failure, or else the current
file position. It is similar to <<lseek>>, except that <[cookie]>
will be passed as the first argument. A NULL <[seekfn]> makes the
stream behave similarly to a pipe in relation to stdio functions that
require positioning. This implementation assumes fpos_t and off_t are
the same type.
<[closefn]> should return -1 on failure, or 0 on success. It is
similar to <<close>>, except that <[cookie]> will be passed as the
first argument. A NULL <[closefn]> merely flushes all data then lets
<<fclose>> succeed. A failed close will still invalidate the stream.
Read and write I/O functions are allowed to change the underlying
buffer on fully buffered or line buffered streams by calling
<<setvbuf>>. They are also not required to completely fill or empty
the buffer. They are not, however, allowed to change streams from
unbuffered to buffered or to change the state of the line buffering
flag. They must also be prepared to have read or write calls occur on
buffers other than the one most recently specified.
The functions <<fropen>> and <<fwopen>> are convenience macros around
<<funopen>> that only use the specified callback.
RETURNS
The return value is an open FILE pointer on success. On error,
<<NULL>> is returned, and <<errno>> will be set to EINVAL if a
function pointer is missing, ENOMEM if the stream cannot be created,
or EMFILE if too many streams are already open.
PORTABILITY
This function is a newlib extension, copying the prototype from BSD.
It is not portable. See also the <<fopencookie>> interface from Linux.
Supporting OS subroutines required: <<sbrk>>.

FUNCTION
<<fwide>>---set and determine the orientation of a FILE stream

fwide
INDEX
_fwide_r
ANSI_SYNOPSIS
#include <wchar.h>
int fwide(FILE *<[fp]>, int <[mode]>);
int _fwide_r(struct _reent *<[ptr]>, FILE *<[fp]>, int <[mode]>);
TRAD_SYNOPSIS
#include <wchar.h>

int _fwide_r(<[ptr]>, <[fp]>, <[mode]>);
struct _reent *<[ptr]>;
FILE *<[fp]>;
int <[mode]>;
DESCRIPTION
When <[mode]> is zero, the <<fwide>> function determines the current
orientation of <[fp]>. It returns a value > 0 if <[fp]> is
wide-character oriented, i.e. if wide character I/O is permitted but
char I/O is disallowed. It returns a value < 0 if <[fp]> is byte
oriented, i.e. if char I/O is permitted but wide character I/O is
disallowed. It returns zero if <[fp]> has no orientation yet; in
this case the next I/O operation might change the orientation (to byte
oriented if it is a char I/O operation, or to wide-character oriented
if it is a wide character I/O operation).
Once a stream has an orientation, it cannot be changed and persists
until the stream is closed, unless the stream is re-opened with freopen,
which removes the orientation of the stream.
When <[mode]> is non-zero, the <<fwide>> function first attempts to set
<[fp]>'s orientation (to wide-character oriented if <[mode]> > 0, or to
byte oriented if <[mode]> < 0). It then returns a value denoting the
current orientation, as above.
RETURNS
The <<fwide>> function returns <[fp]>'s orientation, after possibly
changing it. A return value > 0 means wide-character oriented. A return
value < 0 means byte oriented. A return value of zero means undecided.

C99, POSIX.1-2001.

DESCRIPTION
<<getc>> is a macro, defined in <<stdio.h>>. You can use <<getc>>
to get the next single character from the file or stream
identified by <[fp]>. As a side effect, <<getc>> advances the file's
current position indicator.
For a subroutine version of this macro, see <<fgetc>>.
The <<_getc_r>> function is simply the reentrant version of <<getc>>
which passes an additional reentrancy structure pointer argument: <[ptr]>.
RETURNS
The next character (read as an <<unsigned char>>, and cast to
<<int>>), unless there is no more data, or the host system reports a
read error; in either of these situations, <<getc>> returns <<EOF>>.
You can distinguish the two situations that cause an <<EOF>> result by
using the <<ferror>> and <<feof>> functions.
PORTABILITY
ANSI C requires <<getc>>; it suggests, but does not require, that
<<getc>> be implemented as a macro. The standard explicitly permits
macro implementations of <<getc>> to use the argument more than once;
therefore, in a portable program, you should not use an expression
with side effects as the <<getc>> argument.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

<<getline>> reads a file <[fp]> up to and possibly including the
newline character. The line is read into a buffer pointed to
by <[bufptr]> and designated with size *<[n]>. If the buffer is
not large enough, it will be dynamically grown by <<getdelim>>.
As the buffer is grown, the pointer to the size <[n]> will be
updated.
<<getline>> is equivalent to getdelim(bufptr, n, '\n', fp);
RETURNS
<<getline>> returns <<-1>> if no characters were successfully read,
otherwise, it returns the number of bytes successfully read.
at end of file, the result is nonzero.
PORTABILITY
<<getline>> is a glibc extension.
No supporting OS subroutines are directly required.

FUNCTION
<<gets>>---get character string (obsolete, use <<fgets>> instead)
INDEX
gets
INDEX
_gets_r
ANSI_SYNOPSIS
#include <stdio.h>
char *gets(char *<[buf]>);
char *_gets_r(struct _reent *<[reent]>, char *<[buf]>);
TRAD_SYNOPSIS
#include <stdio.h>
char *gets(<[buf]>)
char *<[buf]>;
char *_gets_r(<[reent]>, <[buf]>)
struct _reent *<[reent]>;
char *<[buf]>;
DESCRIPTION
Reads characters from standard input until a newline is found.
The characters up to the newline are stored in <[buf]>. The
newline is discarded, and the buffer is terminated with a 0.
This is a @emph{dangerous} function, as it has no way of checking
the amount of space available in <[buf]>. One of the attacks
used by the Internet Worm of 1988 used this to overrun a
buffer allocated on the stack of the finger daemon and
overwrite the return address, causing the daemon to execute
code downloaded into it over the connection.
The alternate function <<_gets_r>> is a reentrant version. The extra
argument <[reent]> is a pointer to a reentrancy structure.
RETURNS
<<gets>> returns the buffer passed to it, with the data filled
in. If end of file occurs with some data already accumulated,
the data is returned with no other indication. If end of file
occurs with no data in the buffer, NULL is returned.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

FUNCTION
<<open_memstream>>, <<open_wmemstream>>---open a write stream around an arbitrary-length string
INDEX
open_memstream
INDEX
open_wmemstream
ANSI_SYNOPSIS
#include <stdio.h>
FILE *open_memstream(char **restrict <[buf]>,
size_t *restrict <[size]>);
#include <wchar.h>
FILE *open_wmemstream(wchar_t **restrict <[buf]>,
size_t *restrict <[size]>);
DESCRIPTION
<<open_memstream>> creates a seekable, byte-oriented <<FILE>> stream that
wraps an arbitrary-length buffer, created as if by <<malloc>>. The current
contents of *<[buf]> are ignored; this implementation uses *<[size]>
as a hint of the maximum size expected, but does not fail if the hint
was wrong. The parameters <[buf]> and <[size]> are later stored
through following any call to <<fflush>> or <<fclose>>, set to the
current address and usable size of the allocated string; although
after fflush, the pointer is only valid until another stream operation
that results in a write. Behavior is undefined if the user alters
either *<[buf]> or *<[size]> prior to <<fclose>>.
<<open_wmemstream>> is like <<open_memstream>> just with the associated
stream being wide-oriented. The size set in <[size]> in subsequent
operations is the number of wide characters.
The stream is write-only, since the user can directly read *<[buf]>
after a flush; see <<fmemopen>> for a way to wrap a string with a
readable stream. The user is responsible for calling <<free>> on
the final *<[buf]> after <<fclose>>.
Any time the stream is flushed, a NUL byte is written at the current
position (but is not counted in the buffer length), so that the string
is always NUL-terminated after at most *<[size]> bytes (or wide characters
in case of <<open_wmemstream>>). However, data previously written beyond
the current stream offset is not lost, and the NUL value written during a
flush is restored to its previous value when seeking elsewhere in the string.
RETURNS
The return value is an open FILE pointer on success. On error,
<<NULL>> is returned, and <<errno>> will be set to EINVAL if <[buf]>
or <[size]> is NULL, ENOMEM if memory could not be allocated, or
EMFILE if too many streams are already open.
PORTABILITY
POSIX.1-2008
Supporting OS subroutines required: <<sbrk>>.

FUNCTION
<<putc_unlocked>>---non-thread-safe version of putc (macro)
INDEX
putc_unlocked
INDEX
_putc_unlocked_r
SYNOPSIS
#include <stdio.h>
int putc_unlocked(int <[ch]>, FILE *<[fp]>);
#include <stdio.h>
int _putc_unlocked_r(struct _reent *<[ptr]>, int <[ch]>, FILE *<[fp]>);
DESCRIPTION
<<putc_unlocked>> is a non-thread-safe version of <<putc>> declared in
<<stdio.h>>. <<putc_unlocked>> may only safely be used within a scope
protected by flockfile() (or ftrylockfile()) and funlockfile(). These
functions may safely be used in a multi-threaded program if and only
if they are called while the invoking thread owns the ( FILE *)
object, as is the case after a successful call to the flockfile() or
ftrylockfile() functions. If threads are disabled, then
<<putc_unlocked>> is equivalent to <<putc>>.
The function <<_putc_unlocked_r>> is simply the reentrant version of
<<putc_unlocked>> that takes an additional reentrant structure pointer
argument: <[ptr]>.
RETURNS
See <<putc>>.
PORTABILITY
POSIX 1003.1 requires <<putc_unlocked>>. <<putc_unlocked>> may be
implemented as a macro, so arguments should not have side-effects.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

FUNCTION
<<setbuf>>---specify full buffering for a file or stream
INDEX
setbuf
ANSI_SYNOPSIS
#include <stdio.h>
void setbuf(FILE *<[fp]>, char *<[buf]>);
TRAD_SYNOPSIS
#include <stdio.h>
void setbuf(<[fp]>, <[buf]>)
FILE *<[fp]>;
char *<[buf]>;
DESCRIPTION
<<setbuf>> specifies that output to the file or stream identified by <[fp]>
should be fully buffered. All output for this file will go to a
buffer (of size <<BUFSIZ>>, specified in `<<stdio.h>>'). Output will
be passed on to the host system only when the buffer is full, or when
an input operation intervenes.
You may, if you wish, supply your own buffer by passing a pointer to
it as the argument <[buf]>. It must have size <<BUFSIZ>>. You can
also use <<NULL>> as the value of <[buf]>, to signal that the
<<setbuf>> function is to allocate the buffer.
WARNINGS
You may only use <<setbuf>> before performing any file operation other
than opening the file.
If you supply a non-null <[buf]>, you must ensure that the associated
storage continues to be available until you close the stream
identified by <[fp]>.
RETURNS
<<setbuf>> does not return a result.
PORTABILITY
Both ANSI C and the System V Interface Definition (Issue 2) require
<<setbuf>>. However, they differ on the meaning of a <<NULL>> buffer
pointer: the SVID issue 2 specification says that a <<NULL>> buffer
pointer requests unbuffered output. For maximum portability, avoid
<<NULL>> buffer pointers.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

DESCRIPTION
<<viprintf>>, <<vfiprintf>>, <<vasiprintf>>, <<vsiprintf>>,
<<vsniprintf>>, and <<vasniprintf>> are (respectively) variants of
<<iprintf>>, <<fiprintf>>, <<asiprintf>>, <<siprintf>>, <<sniprintf>>,
and <<asniprintf>>. They differ only in allowing their caller to pass
the variable argument list as a <<va_list>> object (initialized by
<<va_start>>) rather than directly accepting a variable number of
arguments. The caller is responsible for calling <<va_end>>.
<<_viprintf_r>>, <<_vfiprintf_r>>, <<_vasiprintf_r>>,
<<_vsiprintf_r>>, <<_vsniprintf_r>>, and <<_vasniprintf_r>> are
reentrant versions of the above.
RETURNS
The return values are consistent with the corresponding functions:
PORTABILITY
All of these functions are newlib extensions.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

DESCRIPTION
<<viscanf>>, <<vfiscanf>>, and <<vsiscanf>> are (respectively) variants
of <<iscanf>>, <<fiscanf>>, and <<siscanf>>. They differ only in
allowing their caller to pass the variable argument list as a
<<va_list>> object (initialized by <<va_start>>) rather than
directly accepting a variable number of arguments.
RETURNS
The return values are consistent with the corresponding functions:
<<viscanf>> returns the number of input fields successfully scanned,
converted, and stored; the return value does not include scanned
fields which were not stored.
If <<viscanf>> attempts to read at end-of-file, the return value
is <<EOF>>.
If no fields were stored, the return value is <<0>>.
The routines <<_viscanf_r>>, <<_vfiscanf_f>>, and <<_vsiscanf_r>> are
reentrant versions which take an additional first parameter which points to the
reentrancy structure.
PORTABILITY
These are newlib extensions.
Supporting OS subroutines required:
