函数名称：sn_get_sib() - Get the SIB byte of instruction*@insn: &struct insn containing instruction* If necessary, first collects the instruction up to and including the* ModRM byte.

函数原型：void insn_get_sib(struct insn *insn)

返回类型：void

参数：

类型参数名称
struct insn *insn
351  如果 !0 if we've run insn_get_xxx() for this field 则返回
353  如果非 !0 if we've run insn_get_xxx() for this field 则sn_get_modrm - collect ModRM byte, if any*@insn: &struct insn containing instruction* Populates @insn->modrm and updates @insn->next_byte to point past the* ModRM byte, if any. If necessary, first collects the preceding bytes* (prefixes and opcode(s))
355  如果nbytes则
356  modrm等于value
357  如果addr_bytes不等于2且X86_MODRM_MOD(modrm)不等于3且X86_MODRM_RM(modrm)恒等于4则
359  value等于get_next(insn_byte_t, insn)
360  nbytes等于1
363  !0 if we've run insn_get_xxx() for this field 等于1
