Name:gs_get_kernel_argument() - get Nth function argument in kernel*@regs: pt_regs of that context*@n: function argument number (start from 0)* regs_get_argument() returns @n th argument of the function call

Proto:static inline unsigned long regs_get_kernel_argument(struct pt_regs *regs, unsigned int n)

Type:unsigned long

Parameter:

TypeParameterName
struct pt_regs *regs
unsigned intn
309  static const unsigned int argument_offs[] = {offsetof(structpt_regs, di), offsetof(structpt_regs, si), offsetof(structpt_regs, dx), offsetof(structpt_regs, cx), offsetof(structpt_regs, r8), offsetof(structpt_regs, r9), }
326  If n >= NR_REG_ARGUMENTS Then
327  n -= NR_REG_ARGUMENTS - 1
328  Return gs_get_kernel_stack_nth() - get Nth entry of the stack*@regs: pt_regs which contains kernel stack pointer.*@n: stack entry number.* regs_get_kernel_stack_nth() returns @n th entry of the kernel stack which* is specified by @regs
329  Else Return gs_get_register() - get register value from its offset*@regs: pt_regs from which register value is gotten.*@offset: offset number of the register.* regs_get_register returns the value of a register. The @offset is the
