After calling this function, the MIDI input device receives event data in an MIM_DATA message whenever a message with the same event data is sent to the output device driver.
A thru driver is a special form of MIDI output driver. The system will allow only one MIDI output device to be connected to a MIDI input device, but multiple MIDI output devices can be connected to a MIDI thru device. Whenever the given MIDI input device receives event data in an MIM_DATA message, a message with the same event data is sent to the given output device driver (or through the thru driver to the output drivers).
