函数名称：sn_init() - initialize struct insn*@insn: &struct insn to be initialized*@kaddr: address (in kernel memory) of instruction (or copy thereof)*@x86_64: !0 for 64-bit kernel or 64-bit app

函数原型：void insn_init(struct insn *insn, const void *kaddr, int buf_len, int x86_64)

返回类型：void

参数：

类型参数名称
struct insn *insn
const void *kaddr
intbuf_len
intx86_64
48  如果buf_len大于MAX_INSN_SIZE则buf_len等于MAX_INSN_SIZE
51  memset(insn, 0, insn的长度)
52  kernel address of insn to analyze 等于kaddr
53  kernel address of last insn in buffer 等于kaddr加buf_len
54  next_byte等于kaddr
55  x86_64等于如果x86_64则1否则0
56  opnd_bytes等于4
57  如果x86_64则addr_bytes等于8
59  否则addr_bytes等于4
