NAMEfgetpos64(), fopen64(), freopen64(), fseeko64(), fsetpos64(), fstatvfsdev64(), ftello64(), ftw64(), nftw64(), statvfsdev64(), tmpfile64() — non-POSIX standard API interfaces to support large files.

int depth,
int flags); #include <sys/statvfs.h> int statvfsdev64(const char *path, struct statvfs64 *buf); #include <stdio.h> FILE *tmpfile64(void); DESCRIPTIONNew API's to support large files. These API interfaces are not
a part of the POSIX standard and may be removed in the future.
- fgetpos64()
The
fgetpos64()
function is identical to
fgetpos()
except that
fgetpos64()
returns the position in a
fpos64_t
instead of a
fpos_t.
All other functional behaviors, returns, and errors are identical. - fopen64()
The
fopen64()
function is identical to
fopen()
in 64-bit compile environment. The
fopen64()
function returns a pointer to a FILE which can be used to grow the file past
2 GB if desired. All other functional behaviors, returns, and errors are
identical to
fopen(). - freopen64()
The
freopen64()
function is identical to
freopen()
in 64-bit compile environment. The
freopen64()
function returns a pointer to a FILE which can be used to grow the file past
2 GB if desired. All other functional behaviors, returns, and errors are
identical to
freopen(). - fseeko64()
The
fseeko64()
function is identical to
fseeko()
except that
fseeko64()
accepts an
off64_t
for the size parameter instead of
off_t.
All other functional behaviors, returns, and errors are identical. - fsetpos64()
The
fsetpos64()
function is identical to
fsetpos()
except that
fsetpos64()
accepts an
fpos64_t
for the pos parameter instead of
fpos_t.
All other functional behaviors, returns, and errors are identical. - fstatvfsdev64()
The
fstatvfsdev64()
function is identical to
fstatvfsdev()
except that
fstatvfsdev64()
accepts a
struct statvfs64
for the second parameter instead of
struct statvfs.
All other functional behaviors, returns, and errors are identical. - ftello64()
The
ftello64()
function is identical to
ftello()
except that
ftello64()
returns the file position in an
off64_t
instead of an
off_t.
All other functional behaviors, returns, and errors are identical. - ftw64()
The
ftw64()
function is identical to
ftw()
except that it that it utilizes a
struct stat64
as the second parameter to the function
whose pointer is passed to
ftw64().
All other functional behaviors, returns, and errors are identical. - nftw64()
The
nftw64()
function is identical to
nftw()
except that it that it utilizes a
struct stat64
as the second parameter to the function
whose pointer is passed to
nftw64().
All other functional behaviors, returns, and errors are identical. - statvfsdev64()
The
statvfsdev64()
function is identical to
statvfsdev()
except that
statvfsdev64()
accepts a
struct statvfs64
for the second parameter instead of
struct statvfs.
All other functional behaviors, returns, and errors are identical. - tmpfile64()
The
tmpfile64()
function is identical to
tmpfile()
in the 64-bit compile environment. Both interfaces
create a temporary file that is capable of growing
beyond 2GB's if desired. All other
functional behaviors, returns, and errors are identical.
