Hi guys

How call user-space programs(functions) from kernel-space?

Thanks

You don't. Can't be done as specified. Maybe you should give us more details about what you'd like to do.

I want to execute a program in user-space from kernel-space and get output of user-space program in kernel-space program.

I'm not sure about launching a user space app from kernel space. You might need a daemon or you might need to launch the app at startup and have it check for the presence of your kernel space process.
