I don't think that you can access kernel data structures and function in application programs (programs running in user mode over the kernel, making system calls to kernel). Here you are accessing the kernel data structures in your user program. Kernel Data structure can only be exposed to Kernel modules or core kernel. These kernel header files are not made for user application programs.

In particular, I've developed a program like this: #include <linux/sched.h> int main(void){ pid_t pid; .... task_struct process = find_task_by_pid(pid); ... } but the compiler can't find get_task_by_pid function, while this is a function declared in include/linux/sched.h. What's wrong? Are there other methods to access process descriptor pointer? Thanks. Vincenzo Mallozzi. ____________________________________________________________ Yahoo!
