If you don't care about creating a real product, you have more options. Specifically, if you link against the entire kernel you should have access to task_set_special_port, which is a necessary first step. You will also need to use MIG (in kernel mode!) to generate a demux routine. Make sure you don't export your catch_xxx routines, lest they collide with the kernel routines of the same name.

Hello guys, I am definitely stuck with this. Basically, I just tried to set the exception port of a specific task with a fresh new created port (inside my kext). Here is my code: kern_return_t ret = KERN_SUCCESS; ret = ipc_port_alloc(get_task_ipcspace(current_task()), &exception_port_name, &exception_port); IOLog("ipc_port_alloc() ret=%d", ret); if (ret) return kIOReturnError; ret = task_set_exception_ports(target, EXC_MASK_ALL, ipc_port_make_send(exception_port), EXCEPTION_DEFAULT, THREAD_STATE_NONE); IOLog("task_set_exception_ports() ret=%d", ret); if (ret) return kIOReturnError; /* create exception handler thread */ (void) kernel_thread(kernel_task, exception_handler); Unfortunately, this code freeze inside the task_set_exception_ports call. I have no idea on what's going on... Thank you in advance for your help, Nicolas _______________________________________________ Do not post admin requests to the list. They will be ignored.
