神奇的文件格式

Question

来自魔法文件格式手册规则的格式应该是

offset type value message

例如：

0      string   MZ
>0x18  leshort  <0x40   MS-DOS executable
>0x18  leshort  >0x3f   extended PC executable (e.g., MS Windows)

使用这个上下文，我试图理解魔术文件，例如这个其中有类似的规则

# DIY-Thermocam raw data
0   name    diy-thermocam-parser
>0  beshort x   scale %d-

第一条规则是什么意思？至少从手册页来看，名称不是有效类型。并且没有测试组件。

doc该 github 站点目录中的联机帮助页显示：

          name        Define a ``named'' magic instance that can be called
                      from another use magic entry, like a subroutine
                      call.  Named instance direct magic offsets are rela-
                      tive to the offset of the previous matched entry,
                      but indirect offsets are relative to the beginning
                      of the file as usual.  Named magic entries always
                      match.
