Linux kernel 访问用户空间内存访问函数（如-access_ok（）、get_from_user（））时需要包含的头文件的确切路径。？

我在linux-headers-3.2.0-49中搜索了用户内存访问函数。它在uaccess.h头文件中定义，但uaccess.h文件太多。 下面是我通过在linux-headers-3.2.0-49目录中执行“find.-name uaccess.h”得到的结果

./include/linux/uaccess.h
./include/asm-generic/uaccess.h
./arch/frv/include/asm/uaccess.h
./arch/cris/include/asm/uaccess.h
./arch/cris/include/arch-v32/arch/uaccess.h

有人能告诉我访问access\u ok（）、get\u from\u user（）等函数的路径吗？

请参考以下内容。这有一些使用

access\u ok（）

的例子，我首先包括了uaccess.h，正如你所说的，也就是#包括，但在显示错误时：linux/uaccess.h：没有这样的文件或目录我已经用一个例子更新了，你得到了什么错误。最好提供关于错误的更多细节&你试图实现的目标。注意，您应该使用

asm/uaccess.h

而不是

linux/uaccess.h

，我已经更新了之前的帖子。现在添加了include（当我将两个变量C#u include_PATH和CXX_include_PATH设置为/usr/src/linux-headers-3.2.0-65-generic/include:/usr/src/linux-headers-3.2.0-65/arch/x86/include时）。但是现在在MAKE上，但是在MAKE上，我得到了一些新的错误：比如：错误：取消对不完整类型的指针的引用，错误：#错误位不是32或64等
