大家都知道，lib文件是很多obj文件合在一起得到的一个静态库文件。那某一个特定的lib文件，到底是由哪些obj文件组成的呢？

有一个工具可以帮到你，它的名字叫做lib.exe。

还是用LIBC.LIB来举例。我电脑上这个lib文件的位置是在“d:Program FilesMicrosoft Visual StudioVC98LibLIBC.LIB”，进入这个目录。

所有的lib使用选项：

d:Program FilesMicrosoft Visual StudioVC98Lib>lib /
Microsoft (R) Library Manager Version 6.00.8447
Copyright (C) Microsoft Corp 1992-1998. All rights reserved.

usage: LIB [options] [files]

options:

/CONVERT
/DEBUGTYPE:CV
/DEF[:filename]
/EXPORT:symbol
/EXTRACT:membername
/INCLUDE:symbol
/LIBPATH:dir
/LINK50COMPAT
/LIST[:filename]
/MACHINE:{ALPHA|ARM|IX86|MIPS|MIPS16|MIPSR41XX|PPC|SH3|SH4}
/NAME:filename
/NODEFAULTLIB[:library]
/NOLOGO
/OUT:filename
/REMOVE:membername
/SUBSYSTEM:{NATIVE|WINDOWS|CONSOLE|WINDOWSCE|POSIX}[,#[.##]]
/VERBOSE

可以使用list来显示其中的obj文件。

d:Program FilesMicrosoft Visual StudioVC98Lib>lib /list libc.lib

整个列表比较长，所以我又做了个重定向，将输入放到log文件中了。

d:Program FilesMicrosoft Visual StudioVC98Lib>lib /list libc.lib > d: estlibc.log

最终输出有600多行，所以折叠起来，大家可以展开看。
