IMAGE_LOAD_CONFIG_DIRECTORY32 结构的 Reserved1 字段是什么？
What is in the Reserved1 field of the IMAGE_LOAD_CONFIG_DIRECTORY32 structure?
查看 kernelbase.dll 的 IMAGE_LOAD_CONFIG_DIRECTORY32 结构，我看到以下内容：
0:000> dt IMAGE_LOAD_CONFIG_DIRECTORY32 761dc810

`大多数系统 DLL 的 Reserved1 字段似乎设置为 0x800。看起来这个字段的存在也改变了 Ldrp 的行为。有人知道这个字段是关于什么的吗？其中可能的标志值是什么？
好的。我想通了。 IMAGE_LOAD_CONFIG_DIRECTORY32 中的 Reserved1 字段现在用于控制依赖模块的加载方式。到目前为止，我在系统 dll 中找到的唯一值是 0x0800。当此标志存在时，仅在系统目录中搜索依赖模块。
如果您对详细信息感兴趣，请继续阅读。

好的。我想通了。 IMAGE_LOAD_CONFIG_DIRECTORY32 中的 Reserved1 字段现在用于控制依赖模块的加载方式。到目前为止，我在系统 dll 中找到的唯一值是 0x0800。当此标志存在时，仅在系统目录中搜索依赖模块。
