Function linuxcnc_hal_sys::rtapi_outb

pub unsafe extern "C" fn rtapi_outb(byte: c_uchar, port: c_uint)

’rtapi_outb() writes ‘byte’ to ‘port’. May be called from init/cleanup code, and from within realtime tasks. Note: This function does nothing on the simulated RTOS. Note: Many platforms provide an inline outb() that is faster.
