SYSCALL_GET_ARGUMENT(9)		 Machine State	       SYSCALL_GET_ARGUMENT(9)

NAME
       syscall_get_arguments - extract system call parameter values

SYNOPSIS
       void syscall_get_arguments(struct task_struct * task,
				  struct pt_regs * regs, unsigned int i,
				  unsigned int n, unsigned long * args);

ARGUMENTS
       task
	   task of interest, must be blocked

       regs

	   task_pt_regs of task

       i
	   argument index [0,5]

       n
	   number of arguments; n+i must be [1,6].

       args
	   array filled with argument values

DESCRIPTION
       Fetches n arguments to the system call starting with the i´th argument
       (from 0 through 5). Argument i is stored in args[0], and so on. An arch
       inline version is probably optimal when i and n are constants.

       It´s only valid to call this when task is stopped for tracing on entry
       to a system call, due to TIF_SYSCALL_TRACE or TIF_SYSCALL_AUDIT. It´s
       invalid to call this with i + n > 6; we only support system calls
       taking up to 6 arguments.
