Re: New system call and User space header file

["Sachin Gaikwad" <sachin.kernel@xxxxxxxxx>]

Thanks Hareesh for the explanation. That gave me better understanding. :)

@duryodhan : I read the discussion going on that thread.
But
the solution you gave is fine for kernel developers who are going to
test something. What if we have to add system call to kernel release
and then some other user is going to use that. He doesnt have any idea
about system call number we have assigned,...he shud not be bothered
abt that. ????

Whats the solution for that ?

Hey,
I would recommend that you directly call syscall yourself.
#define __NR_syscall_number 324 //(e.g)
#include <linux/unistd.h>
#include <sys/syscall.h>

in the C program do
syscall(324, arg1, arg2)

_syscall2 etc. is a pain to work with, and afaik has been unsupported
for quite some time.
