> - GNU LESSER GENERAL PUBLIC LICENSE
> - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
> -
> - 0. This License Agreement applies to any software library or other
> -program which contains a notice placed by the copyright holder or
> -other authorized party saying it may be distributed under the terms of
> -this Lesser General Public License (also called "this License").
> -Each licensee is addressed as "you".
> -
> - A "library" means a collection of software functions and/or data
> -prepared so as to be conveniently linked with application programs
> -(which use some of those functions and data) to form executables.
> -
> - The "Library", below, refers to any such software library or work
> -which has been distributed under these terms. A "work based on the
> -Library" means either the Library or any derivative work under
> -copyright law: that is to say, a work containing the Library or a
> -portion of it, either verbatim or with modifications and/or translated
> -straightforwardly into another language. (Hereinafter, translation is
> -included without limitation in the term "modification".)
> -
> - "Source code" for a work means the preferred form of the work for
> -making modifications to it. For a library, complete source code means
> -all the source code for all modules it contains, plus any associated
> -interface definition files, plus the scripts used to control
> -compilation
> -and installation of the library.
> -
> - Activities other than copying, distribution and modification are not
> -covered by this License; they are outside its scope. The act of
> -running a program using the Library is not restricted, and output from
> -such a program is covered only if its contents constitute a work based
> -on the Library (independent of the use of the Library in a tool for
> -writing it). Whether that is true depends on what the Library does
> -and what the program that uses the Library does.
> -
> - 1. You may copy and distribute verbatim copies of the Library's
> -complete source code as you receive it, in any medium, provided that
> -you conspicuously and appropriately publish on each copy an
> -appropriate copyright notice and disclaimer of warranty; keep intact
> -all the notices that refer to this License and to the absence of any
> -warranty; and distribute a copy of this License along with the
> -Library.
> -
> - You may charge a fee for the physical act of transferring a copy,
> -and you may at your option offer warranty protection in exchange for a
> -fee.
> -
> - 2. You may modify your copy or copies of the Library or any portion
> -of it, thus forming a work based on the Library, and copy and
> -distribute such modifications or work under the terms of Section 1
> -above, provided that you also meet all of these conditions:
> -
> - a) The modified work must itself be a software library.
> -
> - b) You must cause the files modified to carry prominent notices
> - stating that you changed the files and the date of any change.
> -
> - c) You must cause the whole of the work to be licensed at no
> - charge to all third parties under the terms of this License.
> -
> - d) If a facility in the modified Library refers to a function or a
> - table of data to be supplied by an application program that uses
> - the facility, other than as an argument passed when the facility
> - is invoked, then you must make a good faith effort to ensure that,
> - in the event an application does not supply such function or
> - table, the facility still operates, and performs whatever part of
> - its purpose remains meaningful.
> -
> - (For example, a function in a library to compute square roots has
> - a purpose that is entirely well-defined independent of the
> - application. Therefore, Subsection 2d requires that any
> - application-supplied function or table used by this function must
> - be optional: if the application does not supply it, the square
> - root function must still compute square roots.)
> -
> -These requirements apply to the modified work as a whole. If
> -identifiable sections of that work are not derived from the Library,
> -and can be reasonably considered independent and separate works in
> -themselves, then this License, and its terms, do not apply to those
> -sections when you distribute them as separate works. But when you
> -distribute the same sections as part of a whole which is a work based
> -on the Library, the distribution of the whole must be on the terms of
> -this License, whose permissions for other licensees extend to the
> -entire whole, and thus to each and every part regardless of who wrote
> -it.
> -
> -Thus, it is not the intent of this section to claim rights or contest
> -your rights to work written entirely by you; rather, the intent is to
> -exercise the right to control the distribution of derivative or
> -collective works based on the Library.
> -
> -In addition, mere aggregation of another work not based on the Library
> -with the Library (or with a work based on the Library) on a volume of
> -a storage or distribution medium does not bring the other work under
> -the scope of this License.
> -
> - 3. You may opt to apply the terms of the ordinary GNU General Public
> -License instead of this License to a given copy of the Library. To do
> -this, you must alter all the notices that refer to this License, so
> -that they refer to the ordinary GNU General Public License, version 2,
> -instead of to this License. (If a newer version than version 2 of the
> -ordinary GNU General Public License has appeared, then you can specify
> -that version instead if you wish.) Do not make any other change in
> -these notices.
> -^L
> - Once this change is made in a given copy, it is irreversible for
> -that copy, so the ordinary GNU General Public License applies to all
> -subsequent copies and derivative works made from that copy.
> -
> - This option is useful when you wish to copy part of the code of
> -the Library into a program that is not a library.
> -
> - 4. You may copy and distribute the Library (or a portion or
> -derivative of it, under Section 2) in object code or executable form
> -under the terms of Sections 1 and 2 above provided that you accompany
> -it with the complete corresponding machine-readable source code, which
> -must be distributed under the terms of Sections 1 and 2 above on a
> -medium customarily used for software interchange.
> -
> - If distribution of object code is made by offering access to copy
> -from a designated place, then offering equivalent access to copy the
> -source code from the same place satisfies the requirement to
> -distribute the source code, even though third parties are not
> -compelled to copy the source along with the object code.
> -
> - 5. A program that contains no derivative of any portion of the
> -Library, but is designed to work with the Library by being compiled or
> -linked with it, is called a "work that uses the Library". Such a
> -work, in isolation, is not a derivative work of the Library, and
> -therefore falls outside the scope of this License.
> -
> - However, linking a "work that uses the Library" with the Library
> -creates an executable that is a derivative of the Library (because it
> -contains portions of the Library), rather than a "work that uses the
> -library". The executable is therefore covered by this License.
> -Section 6 states terms for distribution of such executables.
> -
> - When a "work that uses the Library" uses material from a header file
> -that is part of the Library, the object code for the work may be a
> -derivative work of the Library even though the source code is not.
> -Whether this is true is especially significant if the work can be
> -linked without the Library, or if the work is itself a library. The
> -threshold for this to be true is not precisely defined by law.
> -
> - If such an object file uses only numerical parameters, data
> -structure layouts and accessors, and small macros and small inline
> -functions (ten lines or less in length), then the use of the object
> -file is unrestricted, regardless of whether it is legally a derivative
> -work. (Executables containing this object code plus portions of the
> -Library will still fall under Section 6.)
> -
> - Otherwise, if the work is a derivative of the Library, you may
> -distribute the object code for the work under the terms of Section 6.
> -Any executables containing that work also fall under Section 6,
> -whether or not they are linked directly with the Library itself.
> -^L
> - 6. As an exception to the Sections above, you may also combine or
> -link a "work that uses the Library" with the Library to produce a
> -work containing portions of the Library, and distribute that work
> -under terms of your choice, provided that the terms permit
> -modification of the work for the customer's own use and reverse
> -engineering for debugging such modifications.
> -
> - You must give prominent notice with each copy of the work that the
> -Library is used in it and that the Library and its use are covered by
> -this License. You must supply a copy of this License. If the work
> -during execution displays copyright notices, you must include the
> -copyright notice for the Library among them, as well as a reference
> -directing the user to the copy of this License. Also, you must do one
> -of these things:
> -
> - a) Accompany the work with the complete corresponding
> - machine-readable source code for the Library including whatever
> - changes were used in the work (which must be distributed under
> - Sections 1 and 2 above); and, if the work is an executable linked
> - with the Library, with the complete machine-readable "work that
> - uses the Library", as object code and/or source code, so that the
> - user can modify the Library and then relink to produce a modified
> - executable containing the modified Library. (It is understood
> - that the user who changes the contents of definitions files in the
> - Library will not necessarily be able to recompile the application
> - to use the modified definitions.)
> -
> - b) Use a suitable shared library mechanism for linking with the
> - Library. A suitable mechanism is one that (1) uses at run time a
> - copy of the library already present on the user's computer system,
> - rather than copying library functions into the executable, and (2)
> - will operate properly with a modified version of the library, if
> - the user installs one, as long as the modified version is
> - interface-compatible with the version that the work was made with.
> -
> - c) Accompany the work with a written offer, valid for at
> - least three years, to give the same user the materials
> - specified in Subsection 6a, above, for a charge no more
> - than the cost of performing this distribution.
> -
> - d) If distribution of the work is made by offering access to copy
> - from a designated place, offer equivalent access to copy the above
> - specified materials from the same place.
> -
> - e) Verify that the user has already received a copy of these
> - materials or that you have already sent this user a copy.
> -
> - For an executable, the required form of the "work that uses the
> -Library" must include any data and utility programs needed for
> -reproducing the executable from it. However, as a special exception,
> -the materials to be distributed need not include anything that is
> -normally distributed (in either source or binary form) with the major
> -components (compiler, kernel, and so on) of the operating system on
> -which the executable runs, unless that component itself accompanies
> -the executable.
> -
> - It may happen that this requirement contradicts the license
> -restrictions of other proprietary libraries that do not normally
> -accompany the operating system. Such a contradiction means you cannot
> -use both them and the Library together in an executable that you
> -distribute.
> -^L
> - 7. You may place library facilities that are a work based on the
> -Library side-by-side in a single library together with other library
> -facilities not covered by this License, and distribute such a combined
> -library, provided that the separate distribution of the work based on
> -the Library and of the other library facilities is otherwise
> -permitted, and provided that you do these two things:
> -
> - a) Accompany the combined library with a copy of the same work
> - based on the Library, uncombined with any other library
> - facilities. This must be distributed under the terms of the
> - Sections above.
> -
> - b) Give prominent notice with the combined library of the fact
> - that part of it is a work based on the Library, and explaining
> - where to find the accompanying uncombined form of the same work.
> -
> - 8. You may not copy, modify, sublicense, link with, or distribute
> -the Library except as expressly provided under this License. Any
> -attempt otherwise to copy, modify, sublicense, link with, or
> -distribute the Library is void, and will automatically terminate your
> -rights under this License. However, parties who have received copies,
> -or rights, from you under this License will not have their licenses
> -terminated so long as such parties remain in full compliance.
> -
> - 9. You are not required to accept this License, since you have not
> -signed it. However, nothing else grants you permission to modify or
> -distribute the Library or its derivative works. These actions are
> -prohibited by law if you do not accept this License. Therefore, by
> -modifying or distributing the Library (or any work based on the
> -Library), you indicate your acceptance of this License to do so, and
> -all its terms and conditions for copying, distributing or modifying
> -the Library or works based on it.
> -
> - 10. Each time you redistribute the Library (or any work based on the
> -Library), the recipient automatically receives a license from the
> -original licensor to copy, distribute, link with or modify the Library
> -subject to these terms and conditions. You may not impose any further
> -restrictions on the recipients' exercise of the rights granted herein.
> -You are not responsible for enforcing compliance by third parties with
> -this License.
> -^L
> - 11. If, as a consequence of a court judgment or allegation of patent
> -infringement or for any other reason (not limited to patent issues),
> -conditions are imposed on you (whether by court order, agreement or
> -otherwise) that contradict the conditions of this License, they do not
> -excuse you from the conditions of this License. If you cannot
> -distribute so as to satisfy simultaneously your obligations under this
> -License and any other pertinent obligations, then as a consequence you
> -may not distribute the Library at all. For example, if a patent
> -license would not permit royalty-free redistribution of the Library by
> -all those who receive copies directly or indirectly through you, then
> -the only way you could satisfy both it and this License would be to
> -refrain entirely from distribution of the Library.
> -
> -If any portion of this section is held invalid or unenforceable under
> -any particular circumstance, the balance of the section is intended to
> -apply, and the section as a whole is intended to apply in other
> -circumstances.
> -
> -It is not the purpose of this section to induce you to infringe any
> -patents or other property right claims or to contest validity of any
> -such claims; this section has the sole purpose of protecting the
> -integrity of the free software distribution system which is

> -This section is intended to make thoroughly clear what is believed to

> -
> - 12. If the distribution and/or use of the Library is restricted in

> -original copyright holder who places the Library under this License
> -may add an explicit geographical distribution limitation excluding those

> -Notes on running this test suite:
> -
> -To run the test suite, run "make check". All test cases should pass
> -and there should be 0 fails.
> -
> -Several of the test cases require a directory on the filesystem under
> -test for the creation of test files, as well as the generation of
> -error conditions. The test cases assume the directories (or symlinks
> -to directories) are as follows:
> -
> - testdir/
> - - used for general read/write test cases. Must have at
> - least as much free space as the machine has RAM (up
> - to 768MB).
> - testdir.enospc/
> - - a filesystem that has space for writing 8KB out, but
> - fails with -ENOSPC beyond 8KB.
> - testdir.ext2/
> - - must be an ext2 filesystem.

> -The POSIX.1b standard defines a new set of I/O operations which can
> -significantly reduce the time an application spends waiting at I/O. The

> -.B "_POSIX_ASYNCHRONOUS_IO"
> -.
> -
> -These functions are part of the library with realtime functions named
> -.IR "librt"
> -. They are not actually part of the
> -.IR "libc"
> -binary.
> -The implementation of these functions can be done using support in the
> -kernel (if available) or using an implementation based on threads at
> -userlevel. In the latter case it might be necessary to link applications

> -When one or more requests are asynchronously processed, it might be
> -useful in some situations to cancel a selected operation, e.g., if it
> -becomes obvious that the written data is no longer accurate and would
> -have to be overwritten soon. As an example, assume an application, which
> -writes data in files in a situation where new incoming data would have
> -to be written in a file which will be updated by an enqueued request.
> -The POSIX AIO implementation provides such a function, but this function
> -is not capable of forcing the cancellation of the request. It is up to the
> -implementation to decide whether it is possible to cancel the operation
> -or not. Therefore using this function is merely a hint.
> -.B "The libaio implementation does not implement the cancel operation in the"
> -.B "POSIX libraries".
> -.PP
> -The
> -.IR aio_cancel
> -function can be used to cancel one or more

> -.IR aiocbp is not

> -.IR aio_cancel
> -attempts to cancel the specific request pointed to by

> -For requests which were successfully canceled, the normal notification
> -about the termination of the request should take place. I.e., depending
> -on the
> -.IR "struct sigevent"
> -object which controls this, nothing
> -happens, a signal is sent or a thread is started. If the request cannot
> -be canceled, it terminates the usual way after performing the operation.

> -These functions are part of the library with realtime functions named
> -.IR "libaio"
> -. They are not actually part of the
> -.IR "libc"
> -binary.
> -The implementation of these functions can be done using support in the
> -kernel.
> -
> -All IO operations operate on files which were opened previously. There
> -might be arbitrarily many operations running for one file. The
> -asynchronous I/O operations are controlled using a data structure named
