C++ in linux kernel
 

Hi,

First of all I don't want to go discussion regarding C v/s C++ in Linux kernel etc.

I just wanted to know or find out that is there any way available or possible that I can use C++ in my Linux kernel.

Anyone having some suggestion.

Since C++ has the same underlying call structure and uses the same linker, there is no fundamental reason why you can't use C++ for kernel code.

However, there are a number of areas that require some thought:

• Calls to and from the C code will require the use of 'extern "C"' to prevent name mangling so that linking will succeed.
• If you need to use heap space, you will need to write your own new and delete to be compatible with the kernel (ie, making use of kmalloc).
• You will have to be careful about the use of libraries (including the standard ones); many will not be safe to use in a kernel context.

Since the bulk of the operating system is not object oriented, I'm not sure you would gain much by using C++ apart from some minor language improvements.
