[Libusbx-devel] Reverting atexit call of libusb_exit from libusb-compat ?
Hi Recently I've ordered (and received) two USB based I2C/SPI interfaces from NANO River Technology http://nanorivertech.com/viperboard.html. This board is very useful for the LAB work during the evaluation and debugging of the, so called, 'first silicon'. Based on the sample code for Linux from NANO River, I've wrote a small CLI utility to talk to our DUTs from the terminal prompt. Everything works fine. Users are happy. There is just one thing they do not like. They are getting on their screen the following message: [~/I2C]$ i2c 2B AA BB -b 100kbit -U VIPER libusbx: warning [libusb_exit] application left some devices open Yes, I've installed the latest version of the libusbx package. We are running it on CentOS 6.4. Is there a trick (or workaround) to suppress the message ?

Not really a trick or a workaround, you just need to make sure that your application properly closes any devices it has opened before exiting.

No, I can not switch to libusbx directly because: A) the example code from NANO River uses API based on libusb 0.1 B) my programming skills are not adequate to do the conversion C) I plan to support DIMAX SUB-20 board within the same i2c CLI utility D) their API (and example code) is based on libusbx 1.0 So, the libusbx+compat layer is ideal combo for my tiny i2c CLI utility. Or, perhaps, you know for some doc | guidance for "how to map legacy libusb 0.1 API to modern libusbx 1.0 API" ?

Since I am not professional (or even semi professional) programmer, can you, please, point me to the doc | info | code snippet | hint , where I can learn how to close any devices properly. What I did until now, was to take the C++ code example from NANO River Tech web side and compile it on my system (CentOS 6.4). At that time, my CentOS had only the 'old' libusb installed. I am talking here about libusb 0.1 (legacy). Or, to be more specific, NANO River Tech uses http://nanorivertech.com/files/viper/linux/libusb-0.1.12.tar.gz. Their C++ code example works without any issue with the libusb 0.1. No problems with potentially opened devices at exit. There is another I2C interface I want to support with my i2c CLI utility. It is a DIMAX SUB-20 module ( http://www.xdimax.com/sub20/sub20.html ). Their C code example uses libusbx 1.0. So, I decided to install libusbx 1.0.16 + compat layer on the CentOS. This would cover both interface boards. Yes, the both boards work. The NANO board produces warnings about non closed devices at exit. The DIMAX board is OK Igor -- LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.

> Yes sorry my fault, it's just that I'm using linux for development with emacs > and those lines are just too long to actually be readable (yes I'm doing 80 > chars here!). You poor soul. You know they have invented high resolution monitors and editors with nice UI interfaces, where one can be fairly productive, since the 1990s, right? ;) On a more serious note, I know some people swear by 80 chars, but I have yet to see a study indicating that it helps with being more productive and and introducing less bugs. If anything, I'd say it makes the amount of distracting code higher (since your eyes have to parse more lines), and therefore reduces the ability to concentrate on the actual substance. Then again, this is just my subjective opinion from using a nice UI editor on a > 1600px screen. Anyhoo: > I got used to some linux kernel development long time ago and now can't leave > it behind as I really like it. But I can fix that no problem. I did paid > attention to the tabs/whitespace nightmare in libusb, what did I miss? Did I > introduce any spaces where there should be tabs? I'll review my changes again. Since you have a Windows machine to test with, my advice would be to install TortoiseGit (note you'll need to install msysgit first) and fetch your repo. The diff has a very nice UI that will make it very explicit where spaces are used in lieu of tabs, by displaying dots vs arrows. For what is worth, pretty much all the lines you introduced in edde05c45ba7052b01fb25394d0a7267bad4c878 use space in lieu of tabs. There's also some weird stuff where you introduce tabs in comments in d2612f119ab6dc969084e55fa122a66d998826cf. 16f11affc63fe6593036799111c8a4f86011cde4 also has spaces instead of tabs. > BTW shouldn't there be just one code guideline for the hole project? Some people may insist on rigid project-wide guidelines, but I personally don't see that as a necessity, as too constraining. My take is that if you create a new source, you get to pick your styling (as long as it's not too wild). If you follow a source, you follow the styling used by the original author. Especially on a project such as libusb(x), this can help with keeping people who want to introduce a new backend happy for not having to depart from the style they are comfortable with (even if it's something as historical as 80 chars emacs...) I'm not going to comment on MS vs C standards, since I would only have some very negative things to say, and that won't change the fact that, at the end of the day, we have no choice but to deal with how restrictive MSVC is in that respect. --- Reply to this email directly or view it on GitHub: https://github.com/libusbx/libusbx/issues/9#issuecomment-24894839-- LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.
