哪种库内容既不是符号也不是出口？

Question

一般而言，dumpbin /符号< /code>显示从静态库导出的符号，dumpbin /enforts < /code>显示了从动态库导出的符号。

我遇到了一个没有显示出来的库：

(c1) C:\Python-3.10.4\PCbuild\amd64>dumpbin /symbols liblzma.lib
Microsoft (R) COFF/PE Dumper Version 14.31.31104.0

File Type: LIBRARY

(c1) C:\Python-3.10.4\PCbuild\amd64>dumpbin /exports liblzma.lib

到目前为止，它看起来很空，但事实并非如此：

(c1) C:\Python-3.10.4\PCbuild\amd64>dumpbin /all liblzma.lib
Microsoft (R) COFF/PE Dumper Version 14.31.31104.0

因此，它有很多内容，这些内容显示为...在这里发生了什么？这是哪种图书馆？上述输出应该如何解释？
