Listing function prototypes

by M Bealby

Hey everyone, just a quick question. Does anyone know of an existing application that will accept a bunch of header files as input and output a list of function prototypes? It would really help with my code auditing as I'm spending a long time assembling them by hand and it takes a long while. Cheers, Martin

Re: [ros-dev] Patent on FAT

by James Tabor

Hi all, I think this is important to share to the discussion. From one of the developers with FreeDOS, Eric Auer. Thanks, James -------- Original Message -------- Subject: [Freedos-user] re: FAT and other file systems Date: Fri, 13 Jan 2006 17:16:34 +0100 (MET) From: Eric Auer <eric(a)coli.uni-sb.de> Reply-To: freedos-user(a)lists.sourceforge.net To: freedos-user(a)lists.sourceforge.net Hi James, > > And I think it is not more difficult to write HFS or FFS in the kernel > > of FreeDOS than ReiserFS or XFS or all the other candidates. I would like to comment this as follows: The Linux kernel modules for ext3+jbd take 131+59k of memory. Reiserfs takes 243k (243*1000 bytes, too lazy to convert to units of 1024 bytes). On the other hand, FAT core takes 38k and you use it with either MSDOS (8k) or VFAT (13k) implementations. Only the VFAT (long file name enabled) module of Linux is affected by the 3 MS patents mentioned on the MS homepage. > There is no way around this, unless someone will write a disclaimer, "Before > you install FreeDos, do you want to enable Fat32 Patented Features"? Microsoft WANTS you to believe that they patented FAT32. Actually they patented their clever but twisted way to store short and long filenames in the same directory, in a way which allows LFN-unaware operating systems to use the drive without getting confused by the LFN data and usually also without damaging the LFN data either. But you already point that out yourself: > We are > facing the same issue with Ros. When I use FreeDos, I use the basic 8.3 > file system, so I don't see that as a major problem. The point here is the > patent is about LFN, basic 8.3 is not effected. So the disclaimer would only be displayed when you install the DOSLFN package: "Install DOSLFN, which might have patent issues?". FreeDOS as a DOS operating system itself is not affected by that problem. Plus MS does have a disclaimer about their licensing, too: http://www.microsoft.com/whdc/hwdev/download/hardware/fatgen103.pdf which is more than 5 years old by now... allows you to be compatible to all their FAT (including LFN) stuff for the purpose of booting, OS installation, diagnosis, firmware, similar things. They also tell that making/installing operating systems may use all aspects of FAT. You could see this in a pessimist way (you are allowed to develop and compile your OS on a LFN enabled host system) or in a more optimistic way (your operating system itself is allowed to use LFN because it simply is an operating system). MS is targetting two groups at the moment: Vendors of USB sticks who preinstall files on their sticks, and vendors of cams and mp3 players and similar devices. FreeDOS is neither of those. But I did notice that my hardware mp3 player does not support LFN. It only shows the id3 text, if available, as "long song name", and is limited to showing the SHORT file name as song name otherwise. Looks like the vendor of the player did not want to pay MS for each device. Digicams have similar issues - they usually generate filenames like dsc0815 dot jpg and store all extra "title/name" information inside the file (jpeg comment, EXIF data...?). Eric PS: I assume that you mean ReactOS, the free open WinNT clone, when you mention Ros. ReactOS without LFN would not be the same... ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!
