DESCRIPTION
<<fdopen>> produces a file descriptor of type <<FILE *>>, from a
descriptor for an already-open file (returned, for example, by the
system subroutine <<open>> rather than by <<fopen>>).
The <[mode]> argument has the same meanings as in <<fopen>>.
RETURNS
File pointer or <<NULL>>, as for <<fopen>>.
PORTABILITY
<<fdopen>> is ANSI.

DESCRIPTION
Reads at most <[n-1]> characters from <[fp]> until a newline
is found. The characters including to the newline are stored
in <[buf]>. The buffer is terminated with a 0.
The <<_fgets_r>> function is simply the reentrant version of
<<fgets>> and is passed an additional reentrancy structure
pointer: <[ptr]>.
RETURNS
<<fgets>> 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
no data are read, NULL is returned instead.
PORTABILITY
<<fgets>> should replace all uses of <<gets>>. Note however
that <<fgets>> returns all of the data, while <<gets>> removes
the trailing newline (with no indication that it has done so.)
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

DESCRIPTION
<<fread>> attempts to copy, from the file or stream identified by

starting at <[buf]>. <<fread>> may copy fewer elements than
<[count]> if an error, or end of file, intervenes.
<<fread>> also advances the file position indicator (if any) for
<[fp]> by the number of @emph{characters} actually read.
<<_fread_r>> is simply the reentrant version of <<fread>> that
takes an additional reentrant structure pointer argument: <[ptr]>.
RETURNS
The result of <<fread>> is the number of elements it succeeded in
reading.
PORTABILITY
ANSI C requires <<fread>>.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

struct _reent *<[ptr]>;
char *<[file]>;
char *<[mode]>;
FILE *<[fp]>;
DESCRIPTION
Use this variant of <<fopen>> if you wish to specify a particular file
descriptor <[fp]> (notably <<stdin>>, <<stdout>>, or <<stderr>>) for
the file.
If <[fp]> was associated with another file or stream, <<freopen>>
closes that other file or stream (but ignores any errors while closing
it).
<[file]> and <[mode]> are used just as in <<fopen>>.
If <[file]> is <<NULL>>, the underlying stream is modified rather than
closed. The file cannot be given a more permissive access mode (for
example, a <[mode]> of "w" will fail on a read-only file descriptor),
but can change status such as append or binary mode. If modification
is not possible, failure occurs.
RETURNS
If successful, the result is the same as the argument <[fp]>. If the
file cannot be opened as specified, the result is <<NULL>>.
PORTABILITY
ANSI C requires <<freopen>>.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<open>>, <<read>>, <<sbrk>>, <<write>>.

ANSI_SYNOPSIS
#include <stdio.h>
long ftell(FILE *<[fp]>);
off_t ftello(FILE *<[fp]>);
long _ftell_r(struct _reent *<[ptr]>, FILE *<[fp]>);
off_t _ftello_r(struct _reent *<[ptr]>, FILE *<[fp]>);

#include <stdio.h>
long ftell(<[fp]>)

struct _reent *<[ptr]>;
FILE *<[fp]>;
off_t _ftello_r(<[ptr]>, <[fp]>)
struct _reent *<[ptr]>;
FILE *<[fp]>;
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.
The result of <<ftell>>/<<ftello>> is the current position for a file
identified by <[fp]>. If you record this result, you can later
use it with <<fseek>>/<<fseeko>> to return the file to this
position. The difference between <<ftell>> and <<ftello>> is that
<<ftell>> returns <<long>> and <<ftello>> returns <<off_t>>.
In the current implementation, <<ftell>>/<<ftello>> simply uses a character
count to represent the file position; this is the same number that
would be recorded by <<fgetpos>>.
RETURNS
<<ftell>>/<<ftello>> return the file position, if possible. If they cannot do
this, they return <<-1L>>. Failure occurs on streams that do not support
positioning; the global <<errno>> indicates this condition with the
value <<ESPIPE>>.
PORTABILITY
<<ftell>> is required by the ANSI C standard, but the meaning of its
result (when successful) is not specified beyond requiring that it be
acceptable as an argument to <<fseek>>. In particular, other
conforming C implementations may return a different result from
<<ftell>> than what <<fgetpos>> records.
<<ftello>> is defined by the Single Unix specification.
No supporting OS subroutines are required.

FUNCTION

ANSI_SYNOPSIS

char *<[buf]>;
int <[mode]>;

DESCRIPTION
Use <<setvbuf>> to specify what kind of buffering you want for the
file or stream identified by <[fp]>, by using one of the following
values (from <<stdio.h>>) as the <[mode]> argument:
o+
o _IONBF
Do not use a buffer: send output directly to the host system for the
file or stream identified by <[fp]>.
o _IOFBF
Use full output buffering: output will be passed on to the host system
only when the buffer is full, or when an input operation intervenes.
o _IOLBF
Use line buffering: pass on output to the host system at every
newline, as well as when the buffer is full, or when an input
operation intervenes.
o-
Use the <[size]> argument to specify how large a buffer you wish. You
can supply the buffer itself, if you wish, by passing a pointer to a
suitable area of memory as <[buf]>. Otherwise, you may pass <<NULL>>
as the <[buf]> argument, and <<setvbuf>> will allocate the buffer.
WARNINGS
You may only use <<setvbuf>> 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
A <<0>> result indicates success, <<EOF>> failure (invalid <[mode]> or
<[size]> can cause failure).
PORTABILITY
Both ANSI C and the System V Interface Definition (Issue 2) require
<<setvbuf>>. 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.
Both specifications describe the result on failure only as a
nonzero value.

_tempnam_r
ANSI_SYNOPSIS
#include <stdio.h>
char *tmpnam(char *<[s]>);
char *tempnam(char *<[dir]>, char *<[pfx]>);
char *_tmpnam_r(struct _reent *<[reent]>, char *<[s]>);
char *_tempnam_r(struct _reent *<[reent]>, char *<[dir]>, char *<[pfx]>);
TRAD_SYNOPSIS
#include <stdio.h>
char *tmpnam(<[s]>)
char *<[s]>;
char *tempnam(<[dir]>, <[pfx]>)
char *<[dir]>;
char *<[pfx]>;
char *_tmpnam_r(<[reent]>, <[s]>)
struct _reent *<[reent]>;
char *<[s]>;
char *_tempnam_r(<[reent]>, <[dir]>, <[pfx]>)
struct *<[reent]>;
char *<[dir]>;
char *<[pfx]>;
DESCRIPTION
Use either of these functions to generate a name for a temporary file.
The generated name is guaranteed to avoid collision with other files
(for up to <<TMP_MAX>> calls of either function).
<<tmpnam>> generates file names with the value of <<P_tmpdir>>
(defined in `<<stdio.h>>') as the leading directory component of the path.
You can use the <<tmpnam>> argument <[s]> to specify a suitable area
of memory for the generated filename; otherwise, you can call
<<tmpnam(NULL)>> to use an internal static buffer.
<<tempnam>> allows you more control over the generated filename: you
can use the argument <[dir]> to specify the path to a directory for
temporary files, and you can use the argument <[pfx]> to specify a
prefix for the base filename.
If <[dir]> is <<NULL>>, <<tempnam>> will attempt to use the value of
environment variable <<TMPDIR>> instead; if there is no such value,
<<tempnam>> uses the value of <<P_tmpdir>> (defined in `<<stdio.h>>').
If you don't need any particular prefix to the basename of temporary
files, you can pass <<NULL>> as the <[pfx]> argument to <<tempnam>>.
<<_tmpnam_r>> and <<_tempnam_r>> are reentrant versions of <<tmpnam>>
and <<tempnam>> respectively. The extra argument <[reent]> is a
pointer to a reentrancy structure.
WARNINGS
The generated filenames are suitable for temporary files, but do not
in themselves make files temporary. Files with these names must still
be explicitly removed when you no longer want them.
If you supply your own data area <[s]> for <<tmpnam>>, you must ensure
that it has room for at least <<L_tmpnam>> elements of type <<char>>.
RETURNS
Both <<tmpnam>> and <<tempnam>> return a pointer to the newly
generated filename.
PORTABILITY
ANSI C requires <<tmpnam>>, but does not specify the use of
<<P_tmpdir>>. The System V Interface Definition (Issue 2) requires
both <<tmpnam>> and <<tempnam>>.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<getpid>>,
<<isatty>>, <<lseek>>, <<open>>, <<read>>, <<sbrk>>, <<write>>.
The global pointer <<environ>> is also required.
