Hi, I'm Salvatore , from Italy.
How can i lock a my function from time-sharing-scheduling?
I've tried including smp_lock.h that contain lock_kernel
& unlock_kernel() and calling it.
gcc goals but i think that it does not work.
I'm writing some programs about semaphore and shared memory (exactly for resolving problem of reader's and writer's, producer & consumer).
For debug i use some printf and it happen strange things. Printf is buffered and using a fork i found a father's printf in the system calls of the process created.
(see strace -ff -T -tt exe).
Than i'm writing a function (print2debug()) that lock
the kernel so all state(variables, contest in which printf appear) are ok while execute the debug function.
I thank you for any reply!!! GoodBye from Naples.
