===================

|
|
NOTE: If CONFIG_FAT_LFN is defined in your NuttX configuration file, then
|
|
there may be some legal, patent issues. The following was extracted from
|
|
the entry "File Allocation Table from Wikipedia, the free encyclopedia:
|
|
|
|
"On December 3, 2003 Microsoft announced it would be offering licenses
|
|
for use of its FAT specification and 'associated intellectual property',
|
|
at the cost of a US$0.25 royalty per unit sold, with a $250,000 maximum
|
|
royalty per license agreement.

|
|
Method and system for accessing a file using file names having
|
|
different file name formats. ...
|
|
o "U.S. Patent 5,579,517 (http://www.google.com/patents?vid=5579517) -
|
|
Common name space for long and short filenames. ...

|
|
o "U.S. Patent 6,286,013 (http://www.google.com/patents?vid=6286013) -
|
|
Method and system for providing a common name space for long and
|
|
short file names in an operating system. ...
|
|
|
|
"Many technical commentators have concluded that these patents only cover
|
|
FAT implementations that include support for long filenames, and that
|
|
removable solid state media and consumer devices only using short names
|
|
would be unaffected. ..."
