It's a syscall. That can't be in a module. It's unlikely that it's actualy exported (acoording to http://lxr.linux.no, it is not)-- all symbols that can be used by modules must be explicitely makred as such. That function is declared asmlinkage. It can't be called without a proper prototype, because asmlinkage changes the calling convention. You don't want to use that function anyway. The problem is, that in a kernel thread (you are working in kernel thread, right) you don't have file descriptor table available. So you don't want a file descriptor, you want the struct socket structure. That is, you want to use the sock_create function. After that, you want to call it's methods (functions in the .ops element). ------------------------------------------------------------------------------- Jan 'Bulb' Hudec <bulb@xxxxxx>
