Re: Chapter 24: Process Management Initial Release

Hey Mike, I tried following chapter 24, and encountered a few errors: First, in terminateThread you call a function called terminateProcess which does not exist, perhaps you missed it? Second, in the process type, there is no such function as getCurrentProcess, again, perhaps if you can write it? An...

Re: For Mike...

Hey Mike,

For the next chapters, could you please add a chapter regarding how to make the OS use an hard drive? (let's say in FAT16/FAT32)

Oh, and another thing, perhaps adding a chapter regarding single & multi tasking?

Re: Problem in writing to a text file

That's the point, I always used VirtualBox to test the OS. The code I created in fsys.cpp: int volWriteFile(const char* filename, const char* DirectoryName, char* Buffer) { // The const char* DirectoryName variable will receive the current directory unsigned char device = 'a'; if(strcmp(filename, &q...

Problem in writing to a text file

OK, so what I basically did was to reverse the read method. In the main kernel file, I did a method which takes the file path from the user, and in the file system driver I created a method which does the writing. However, since I changed the fsys file (file system driver) both the read and write op...

Re: How to read input from user into a double-type variable

That could be helpful if I could use Microsoft C++ libraries, but, since I can't, I am looking for a way to actually write a function that will allow me to take a string, and put inside a double variable.

How to read input from user into a double-type variable

Hey, I am trying to read input from the user and put it inside a double-type variable? I developed a function who does the sqrt function to a number, the problem is that I can't read any double-type input from the user, only int-type. Does anybody knows how to write such a function that will enable ...

Re: User mode not working--Please HELP!!--

Hmm, bochs and vpc doesn't like win7 x64, apparently.

I'm sorry I'm asking so much about it, but when do you plan to release chapter 22 update?

And any estimate time for chapter 24??

User mode not working--Please HELP!!--

Hey,

I tried to implement the user mode as written in the Chapter 23 demo, but when I try to run it, I always get a "General Protection Fault" error in VirtualBox.

I also tried to run the demo as specified by Mike, but I get the same result (again, in VirtualBox)

How can I fix this??

Re: The Visual Studio file

Look, I tried it with VS2010, and it was OK. There were some glitches, but not something really interrupting the work,

Mainly in the build system, sometimes it can't find some files.
