darling-newlkm | Darling 's new kernel module

To install IOKit headers, see additional comments in [iokit/IOKit/Makefile](). XNU installs header files at the following locations -. Kernel.framework is used by kernel extensions.\ The System.framework and /usr/include are used by user level applications. \ The header files in framework’s PrivateHeaders are only available for Apple Internal Development . The directory containing the header file should have a Makefile that creates the list of files that should be installed at different locations. If you are adding first header file in a directory, you will need to create Makefile similar to xnu/bsd/sys/Makefile. Add your header file to the correct file list depending on where you want to install it. The default locations where the header files are installed from each file list are -. The Makefile combines the file lists mentioned above into different install lists which are used by build system to install the header files. If the install list that you are interested does not exist, create it by adding the appropriate file lists. The default install lists, its member file lists and their default location are described below -. If you want to install the header file in a sub-directory of the paths described in (1), specify the directory name using two variables INSTALL_MI_DIR and EXPORT_MI_DIR as follows -. A single header file can exist at different locations using the steps mentioned above. However it might not be desirable to make all the code in the header file available at all the locations. For example, you want to export a function only to kernel level but not user level.

PRIVATE : If true, code is available to all of the xnu kernel and is not available in kernel extensions and user level header files. The header files installed in all the paths described above in (1) will not have code enclosed within this macro.
KERNEL_PRIVATE : If true, code is available to all of the xnu kernel and Apple internal kernel extensions.
BSD_KERNEL_PRIVATE : If true, code is available to the xnu/bsd part of the kernel and is not available to rest of the kernel, kernel extensions and user level header files. The header files installed in all the paths described above in (1) will not have code enclosed within this macro.
KERNEL : If true, code is available only in kernel and kernel extensions and is not available in user level header files. Only the header files installed in following paths will have the code - $(DSTROOT)/System/Library/Frameworks/Kernel.framework/Headers $(DSTROOT)/System/Library/Frameworks/Kernel.framework/PrivateHeaders you should check [Testing the kernel][] for details.
