Writing an operating system using c libraries

Why bother with header-style libraries? This allows for the programmers to write other parts of the library that utilize the functions in the headers without actually knowing what the definitions of those functions are.

Writing an operating system using c libraries

Other operating systems use other formats, and since DLLs are binary they cannot generally be used on other processor architectures such as ARM devices.

However, other DLLs don't have this flexibility Furthermore, code written in C will typically require the. NET framework or at least the. NET runtime in order to work. Different Windows operating systems support different. Code targeting the desktop might not work on mobile devices. NET libraries are not currently available on non-Windows systems.

While your C -written DLL will be of little use on non-Windows systems, there are a few possibilities to make your code more widely usable: However, WINE is not viable mechanism for making libraries usable. Unfortunately, the WINE project — as a volunteer effort — is lagging years behind in Windows features.

The Mono project offers a reimplemenation of the. NET framework and the C language which runs on a variety of devices and operating system, including Linux and mobile devices. You could then recompile your library for each target system using Mono. However, the Mono implementation is lagging years behind, so you will not be able to use modern language features or newer additions to.

Porting your code to Mono is possible, but may take some effort. Microsoft has announced that it will add support for non-Windows systems, but until then Mono is your best bet.

If you are content with only targeting Windows systems, offer compiled packages via NuGet. This makes it easy for other C programmers to get and incorporate your library. Consider publishing the source code. This makes debugging much easier for users of your library, and helps others help you.

GitHub is a good place to start of you're using Git for version control. Forget Cand use a language that's really cross-platform. However, you'll always lock into a specific ecosystem. Nearly any language can easily interface with a library written in C, but writing C is difficult even more so if you want your code to be portable.

There may be more newer ways, but it's been a couple of years since I last wrote C ….The C Standard Library, also known as ISO C Library is a collection of macros, types and functions for tasks such as input/output processing, string handling, memory management, mathematical computations and many other operating system services.

It is specified in the C standard (e.g. the C11 standard). At the moment I'm learning objective c , and soon I plan on learning assembly language, so I can write an operating system.

I know it won't be easy, and I know it . The C Standard Library, also known as ISO C Library is a collection of macros, types and functions for tasks such as input/output processing, string handling, memory management, mathematical computations and many other operating system services.

It is specified in the C standard (e.g.

the C11 standard). Be careful, C++ is pretty heavyweight for an OS kernel. There are services like exceptions that you'll have to support with a runtime library. It won't feel like C++ until you add a heap. Kernels are very sensitive to where objects are allocated; the one-heap model usually used in C++ isn't really suitable.

You can send output to and read input from the operating system by using named pipes. For example, you may want to compress a data set or send it to a tape management system without creating intermediate files. But, on the other hand, there are several implementations of the C library, and also, the GNU C library is available for others operating systems, such as Windows.

And I'm sure that there are other languages out there that call the OS without using the standard C library.
