Hi,
I want to call some functions of a user space program from a kernel module. I cannot obviously put the code of the user space program in the kernel module as I dont have the libraries for that in the kernel space. So can anyone tell me how to be able to call user space programs, or link to them through kernel modules?
Thanks a lot

You can write a small plication in user space that call the function and retun to the kernel module.

Hi
You can write a function in user space which will call the function in kernal by passing the address of the function(using function pointer) provided that the function in kernal has one of its arguments as a function pointer.
Thanks
