• int i;
• struct pt_regs regs;
• memset(&regs, 0, sizeof(regs));
• regs.regs[0] = func_id;
• if (args) {

• for (i = 0; i < arg_len; i++)
  

• 	regs.regs[i + 1] = args[i];
  

Is this memcpy() ?

• }
• smc_call(&regs);
• if (ret_arg) {

• for (i = 0; i < ret_len; i++)
  

• 	ret_arg[i] = regs.regs[i + 1];
  

memcpy() ?
