d)  If a facility in the modified Librar y 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 effor t to ensure that, in the event an application does not supply such function or table, the 

facility still operates, and per forms whatever par t of its purpose remains meaningful.

(For example, a function in a librar y 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 Librar y, 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 par t of a whole which is a work based on the Librar y, the distribution of the whole 

must be on the terms of this License, whose permissions for other licensees ex tend to the entire whole, and thus 

to each and ever y par t 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 Librar y.
In addition, mere aggregation of another work not based on the Librar y with the Librar y (or with a work based on 

the Librar y) 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 ordinar y GNU General Public License instead of this License to a given 

copy of the Librar y. To do this, you must alter all the notices that refer to this License, so that they refer to the 

ordinar y GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of 

the ordinar y 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 ordinar y 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 par t of the code of the Librar y into a program that is not a librar y.

4. 

You may copy and distribute the Librar y (or a por tion 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 par ties are not compelled to copy the source along with the object code.

5.

  A program that contains no derivative of any por tion of the Librar y, but is designed to work with the Librar y 

by being compiled or linked with it, is called a “work that uses the Librar y”. Such a work, in isolation, is not a 

derivative work of the Librar y, and therefore falls outside the scope of this License.
However, linking a “work that uses the Librar y” with the Librar y creates an executable that is a derivative of the 

Librar y (because it contains por tions of the Librar y), rather than a “work that uses the librar y”. The executable is 

therefore covered by this License. 

Section 6 states terms for distribution of such executables.
When a “work that uses the Librar y” uses material from a header file that is par t of the Librar y, the object code 

for the work may be a derivative work of the Librar y even though the source code is not. 

Whether this is true is especially significant if the work can be linked without the Librar y, or if the work is itself a 

librar y. 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 por tions of the Librar y will still 

fall under Section 6.)
Other wise, if the work is a derivative of the Librar y, 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 

Librar y itself.

6.

  As an exception to the Sections above, you may also combine or link a “work that uses the Librar y” with the 

Librar y to produce a work containing por tions of the Librar y, 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.
