I am new to Linux kernel stuffs. How are Kernel API and syscalls differ from each other? On 2 June 2014 13:43, Varka Bhadram <varkab@cdac.in> wrote:
These two are not the system calls. they are the Kernel API's to transfer the data from user address space to the kernel address space.

Hi,
Here's an exhaustive list <http://man7.org/linux/man-pages/man2/syscalls.2.html> of Linux syscall, but I can't find get_user() and put_user() API. Why is it so? What am I missing? _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
