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
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
independent and separate works in them-selves, then this License, and its terms, do not
apply to those sections when you distribute them as sepa-rate 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 un-der 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.
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
assessors, 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
