"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.
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
