-.TH LSEEK64 3 2014-08-19 "Linux" "Linux Programmer's Manual"
-.SH NAME
-lseek64 \- reposition 64-bit read/write file offset
-.SH SYNOPSIS
-.BR "#define _LARGEFILE64_SOURCE" " /* See feature_test_macros(7) */"
-.br
-.B #include <sys/types.h>
-.br
-.B #include <unistd.h>
-.sp
-.BI "off64_t lseek64(int " fd ", off64_t " offset ", int " whence );
-.SH DESCRIPTION
-The
-.BR lseek (2)
-family of functions reposition the offset of the open file associated
-with the file descriptor
-.I fd
-to
-.I offset
-bytes relative to the start, current position, or end of the file,
-when
-.I whence
-has the value
-.BR SEEK_SET ,
-.BR SEEK_CUR ,
-or
-.BR SEEK_END ,
-respectively.
-.LP
-For more details, return value, and errors, see
-.BR lseek (2).
-.PP
-Four interfaces are available:
-.BR lseek (2),
-.BR lseek64 (),
-.BR llseek (2),
-and the raw system call
-.BR _llseek (2).
-.SS lseek
-Prototype:
-.nf
-.sp
-.in +4n
-.BI "off_t lseek(int " fd ", off_t " offset ", int " whence );
-.in
-.fi
-.sp
-.BR lseek (2)
-uses the type
-.IR off_t .
-This is a 32-bit signed type on 32-bit architectures, unless one
-compiles with
-.nf
-.sp
-.in +4n
-#define _FILE_OFFSET_BITS 64
-.in
-.sp
-.fi
-in which case it is a 64-bit signed type.
-.SS lseek64
-Prototype:
-.nf
-.sp
-.in +4n
-.BI "off64_t lseek64(int " fd ", off64_t " offset ", int " whence );
-.in
-.fi
-.sp
-The library routine
-.BR lseek64 ()
-uses a 64-bit type even when
-.I off_t
-is a 32-bit type.
-Its prototype (and the type
-.IR off64_t )
-is available only when one compiles with
-.nf
-.sp
-.in +4n
-#define _LARGEFILE64_SOURCE
-.in
-.sp
-.fi
-The function
-.BR lseek64 ()
-.\" in glibc 2.0.94, not in 2.0.6
-is available since glibc 2.1, and is defined to be an alias for
-.BR llseek ().
-.SS llseek
-Prototype:
-.nf
-.sp
-.in +4n
-.BI "loff_t llseek(int " fd ", loff_t " offset ", int " whence );
-.in
-.fi
-.sp
-The type
-.I loff_t
-is a 64-bit signed type.
-The library routine
-.BR llseek ()
-.\" in libc 5.0.9, not in 4.7.6
-is available in the glibc and works without special defines.
-However, the glibc headers do not provide a prototype.
-Users should add
-the above prototype, or something equivalent, to their own source.
-When users complained about data loss caused by a miscompilation of
-.BR e2fsck (8),
-glibc 2.1.3 added the link-time warning
-.sp
-.in +4n
-"the \`llseek\' function may be dangerous; use \`lseek64\' instead."
-.in
-.sp
-This makes this function unusable if one desires a warning-free
-compilation.
-.SS _llseek
-All the above functions are implemented in terms of this system call.
-The prototype is:
-.nf
-.sp
-.in +4n
-.BI "int _llseek(int " fd ", off_t " offset_hi ", off_t " offset_lo ,
-.BI " loff_t *" result ", int " whence );
-.in
-.fi
-.sp
-For more details, see
-.BR llseek (2).
-.SH ATTRIBUTES
-.SS Multithreading (see pthreads(7))
-The
-.BR lseek64 ()
-function is thread-safe.
