Hello all, I'm a newbie (at kernel programming) and am experimenting with a driver that will send messages to a user client. However, when I use 'mach_msg' in my code, it fails to load at run time because the kernel linker cannot find "_mach_msg". I also notice that the 'struct mach_msg_type_t' is missing (along with a whole bunch of things) from the <mach/message.h> header file. Any help, or pointers to some more detailed documentation for using mach_msg to communicate from the kernel to a user client would be much appreciated. This email sent to site_archiver@lists.apple.com
