FUNCTION
<<fgetpos64>>---record position in a large stream or file
INDEX
fgetpos64
ANSI_SYNOPSIS
#include <stdio.h>
int fgetpos64(FILE *<[fp]>, _fpos64_t *<[pos]>);
TRAD_SYNOPSIS
#include <stdio.h>
int fgetpos64(<[fp]>, <[pos]>)
FILE *<[fp]>;
_fpos64_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 <<fgetpos64>> to report on the current position for a file
identified by <[fp]> that was opened by <<fopen64>>; <<fgetpos>> will write
a value representing that position at <<*<[pos]>>>. Later, you can
use this value with <<fsetpos64>> to return the file to this
position.
In the current implementation, <<fgetpos64>> simply uses a character
count to represent the file position; this is the same number that
would be returned by <<ftello64>>.
RETURNS
<<fgetpos64>> returns <<0>> when successful. If <<fgetpos64>> fails, the
result is <<1>>. Failure occurs on streams that do not support
positioning or streams not opened via <<fopen64>>; the global <<errno>>
indicates these conditions with the value <<ESPIPE>>.
PORTABILITY
<<fgetpos64>> is a glibc extension.
No supporting OS subroutines are required.

fseeko64
ANSI_SYNOPSIS

TRAD_SYNOPSIS

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 <<fseeko64>> to set the position for the file identified by
<[fp]> that was opened via <<fopen64>>. The value of <[offset]> determines
the new position, in one of three ways selected by the value of <[whence]>
(defined as macros in `<<stdio.h>>'):
<<SEEK_SET>>---<[offset]> is the absolute file position (an offset
from the beginning of the file) desired. <[offset]> must be positive.
<<SEEK_CUR>>---<[offset]> is relative to the current file position.
<[offset]> can meaningfully be either positive or negative.
<<SEEK_END>>---<[offset]> is relative to the current end of file.
<[offset]> can meaningfully be either positive (to increase the size
of the file) or negative.
See <<ftello64>> to determine the current file position.
RETURNS
<<fseeko64>> returns <<0>> when successful. On failure, the
result is <<EOF>>. The reason for failure is indicated in <<errno>>:
either <<ESPIPE>> (the stream identified by <[fp]> doesn't support
repositioning or wasn't opened via <<fopen64>>) or <<EINVAL>>
(invalid file position).
PORTABILITY
<<fseeko64>> is a glibc extension.
Supporting OS subroutines required: <<close>>, <<fstat64>>, <<isatty>>,
<<lseek64>>, <<read>>, <<sbrk>>, <<write>>.

FUNCTION
<<fsetpos64>>---restore position of a large stream or file
INDEX
fsetpos64
ANSI_SYNOPSIS
#include <stdio.h>
int fsetpos64(FILE *<[fp]>, const _fpos64_t *<[pos]>);
TRAD_SYNOPSIS
#include <stdio.h>
int fsetpos64(<[fp]>, <[pos]>)
FILE *<[fp]>;
_fpos64_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 <<fsetpos64>> to return the large file identified by <[fp]> to a
previous position <<*<[pos]>>> (after first recording it with <<fgetpos64>>).
See <<fseeko64>> for a similar facility.
RETURNS
<<fgetpos64>> returns <<0>> when successful. If <<fgetpos64>> fails, the
result is <<1>>. The reason for failure is indicated in <<errno>>:
either <<ESPIPE>> (the stream identified by <[fp]> doesn't support
64-bit repositioning) or <<EINVAL>> (invalid file position).
PORTABILITY
<<fsetpos64>> is a glibc extension.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek64>>, <<read>>, <<sbrk>>, <<write>>.

FUNCTION
<<ftello64>>---return position in a stream or file
INDEX
ftello64
ANSI_SYNOPSIS
#include <stdio.h>
_off64_t ftello64(FILE *<[fp]>);
TRAD_SYNOPSIS
#include <stdio.h>
_off64_t ftello64(<[fp]>)
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 <<ftello64>> is the current position for a large file
identified by <[fp]>. If you record this result, you can later
use it with <<fseeko64>> to return the file to this
position. The difference between <<ftello>> and <<ftello64>> is that
<<ftello>> returns <<off_t>> and <<ftello64>> is designed to work
for large files (>2GB) and returns <<_off64_t>>.
In the current implementation, <<ftello64>> simply uses a character
count to represent the file position; this is the same number that
would be recorded by <<fgetpos64>>.
The function exists only if the __LARGE64_FILES flag is defined.
An error occurs if the <[fp]> was not opened via <<fopen64>>.
RETURNS
<<ftello64>> returns the file position, if possible. If it cannot do
this, it returns <<-1>>. Failure occurs on streams that do not support
positioning or not opened via <<fopen64>>; the global <<errno>> indicates
this condition with the value <<ESPIPE>>.
PORTABILITY
<<ftello64>> is a glibc extension.
No supporting OS subroutines are required.

@chapter Large File Input and Output (@file{stdio.h})
This chapter comprises additional functions to manage large files which
are potentially larger than 2GB.
The underlying facilities for input and output depend on the host
system, but these functions provide a uniform interface.
The corresponding declarations are in @file{stdio.h}.
@menu
* fopen64:: Open a large file
* freopen64:: Open a large file using an existing file descriptor
* fsetpos64:: Restore position of a large stream or file
* fgetpos64:: Get position of a large stream or file

FUNCTION
<<tmpfile64>>---create a large temporary file
INDEX
tmpfile64
INDEX
_tmpfile64_r
ANSI_SYNOPSIS
#include <stdio.h>
FILE *tmpfile64(void);
FILE *_tmpfile64_r(void *<[reent]>);
TRAD_SYNOPSIS
#include <stdio.h>
FILE *tmpfile64();
FILE *_tmpfile64_r(<[reent]>)
char *<[reent]>;
DESCRIPTION
Create a large temporary file (a file which will be deleted automatically),
using a name generated by <<tmpnam>>. The temporary file is opened with
the mode <<"wb+">>, permitting you to read and write anywhere in it
as a binary file (without any data transformations the host system may
perform for text files). The file may be larger than 2GB.
The alternate function <<_tmpfile64_r>> is a reentrant version. The
argument <[reent]> is a pointer to a reentrancy structure.
Both <<tmpfile64>> and <<_tmpfile64_r>> are only defined if __LARGE64_FILES
is defined.
RETURNS
<<tmpfile64>> normally returns a pointer to the temporary file. If no
temporary file could be created, the result is NULL, and <<errno>>
records the reason for failure.
PORTABILITY
<<tmpfile64>> is a glibc extension.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<getpid>>,
<<isatty>>, <<lseek64>>, <<open64>>, <<read>>, <<sbrk>>, <<write>>.
<<tmpfile64>> also requires the global pointer <<environ>>.
