LICENSE AGREEMENTS (continued)
End User License Agreements for Operating System Software (continued)
When a “work that uses the Library” uses material from a header fi le 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 signifi cant 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 defi ned by law.
If such an object fi le 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 fi le 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.
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 modifi cation of the work for the customer’s own use and reverse engineering for
debugging such modifi cations.
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 modifi ed
executable containing the modifi ed Library. (It is understood that the user who changes the contents of defi nitions
fi les in the Library will not necessarily be able to recompile the application to use the modifi ed defi nitions.)
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 modifi ed version of the library, if the user installs
one, as long as the modifi ed 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
specifi ed 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 specifi ed 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.
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:
