FAT Long File Names |
|
|
^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
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. |
|
|
|
|
|
o "U.S. Patent 5,745,902 (http://www.google.com/patents?vid=5745902) - |
|
|
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 5,758,352 (http://www.google.com/patents?vid=5758352) - |
|
|
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. ..." |
|
|
|
|
|
This Wikipedia entry has been updated with recent legal decisions in favor |
|
|
of Microsoft. Refer to: |
|
|
|
|
|
http://en.wikipedia.org/wiki/File_Allocation_Table#Legal_issues |
|
|
|
|
|
So you have been forewarned: Use the long filename at your own risk! |

The University of Michigan uses a modified BSD license equivalent to |
|
|
the NuttX license. The University of California code uses the original |
|
|
BSD license and requires that I state the following: |

^^^^^^ |
|
|
|
|
|
If you enable floating point conversions with CONFIG_LIBC_FLOATINGPOINT, |
|
|
then some files with an unmodified BSD license will be included. That |
|
|
license is similar to the above (modified) BSD license, but has an |
|
|
additional requirement that I state the following: |
|
|
|

|
"This product includes software developed by the University of |

libc/string/lib_vikmemcpy.c |
|

^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
|
|
|
|
If you enable CONFIG_MEMCPY_VIK, then you will build with the optimized |
|
|
version of memcpy from Daniel Vik. Licensing information for that version |
|
|
of memcpy() follows: |

libc/math |
|

^^^^^^^^^ |
|

If you enable CONFIG_LIB, you will build the math library at libc/math. |

OS by Nick Johnson (https://github.com/nickbjohnson4224/rhombus). This |
