macrothread_get_kernel_port

#define thread_get_kernel_port(thread, port) (thread_get_special_port((thread), THREAD_KERNEL_PORT, (port)))

kern_return_t thread_get_kernel_port(thread_t thread, mach_port_t *kernel_port)

The function thread_get_kernel_port is equivalent to the function thread_get_special_port with the which_port argument set to THREAD_KERNEL_PORT.

macrothread_set_kernel_port

#define thread_set_kernel_port(thread, port) (thread_set_special_port((thread), THREAD_KERNEL_PORT, (port)))

kern_return_t thread_set_kernel_port(thread_t thread, mach_port_t kernel_port)

The function thread_set_kernel_port is equivalent to the function thread_set_special_port with the which_port argument set to THREAD_KERNEL_PORT.
