The way these languages work means that they cannot effectively be loaded into ring0. share edited Sep 27 '11 at 13:57 Tim Cooper 96.8k21183194 answered Mar 25 '09 at 22:14 vladr 49.6k13106121 Are you so sure about the 'not possible'-part, that you make can anyone suggest a guide line? For most developers, it means programming at the lowestlevel in the system, talking directly to, and controlling, hardware. Source

This version has been successfully tested on Macintosh, Windows 95 and Solaris. So language-wise, there is technically no problem. So, pick what interests you most, perhaps by surveying development lists or bug trackers, and see what kinds of impact you want to make. Success!

  • morefromWikipedia Type safety In computer science, type safety is the extent to which a programming language discourages or prevents type errors.
  • JDDK FCS Candidate 2 Release JDDK FCSc2 requires JDK 1.1.6 or greater, but it does not yet function correctly when using JDK 1.2 (Java 2).
  • You could replace the GC with a simple reference counting mechanism (and add a mechanism to break cycles).
  • Similar Threads Drivers License Reader Device drivers How can we get Driver Info?
  • If anyone interested, here's my source code for simple memory char driver. /** * simplemem.c * * Demonstrate simple driver to read/write kernel memory * Adapted from LDD Ch #3, and
  • I have written such device drivers on top of MOST in an automotive application.

A device driver programmer will know how to use locks, queues, and other kernel interfaces to get their hardware working properly and responsively, but he won't be as likely to fix With this in hand, you're a lot closer to being able to compile device drivers than you were before. The result is that there is a high diversity of protocols. So, I'm assuming, that some of you on stackoverflow work in a professional capacity doing just what I would like to do.

The goal of Java is to be cross-platform, so it lacks the OS-specific features that would make writing device drivers easy. What platforms did you use to work your way there? I only interested in ‘open' (handles the driver opening), ‘release' (handles the driver closing), ‘read' (handles data transfer from driver to user application), and ‘write' (handles data transfer from user application https://embeddedfreak.wordpress.com/2009/02/05/linux-device-driver-programming-for-java-programmer/ If you can answer this question, you should find a way to make it possible.

The employer pays the recruitment fee and the recruiter will help sell you in a way that you cannot do on your own. How are banners kept upright? Especially in manufacturing (e.g. Also already exist drivers in userspace, at least the userspace-part should be no problem to implement in Java.

Which Choice Best Explains The Connection Between Machine Language And Assembly Language?

Because you can write an operating system in Java and C#, and then, should be able to write device drivers for it.

The javax.comm package is available separately at http://java.sun.com/products/javacomm and should run with the JDDK on any OS with JDK 1.1.6 support. Some vendors prefer simple plain-text protocols, but others prefer complex binary protocols with CRC codes, framing, ... Again, once you have verifiable experience to put on your resume, it opens doors.

Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting for cost allocation of processor time, mass storage, printing, and other resources.

System programmers write daemons, utilities, and other tools for automating common or difficult tasks. you need machine code to access the bits and bytes. –Peter Parker Mar 25 '09 at 23:01 en.wikipedia.org/wiki/PicoJava –TofuBeer Mar 25 '09 at 23:04 @mnemeth, extremely sure; This is a technique that can be used to create very high performance systems.

Why did Denethor, Lord of Gondor, burn himself to death? Check This Out But, if your device communicates using, say, a serial port or USB, and if the OS doesn't necessarily need to be aware of the device (only your application will access the
