MXC-6300
windowHandle
Handle to the destination window for a Windows message
when the specified INT event occurs. If windowHandle is 0, no
Windows messages will be sent.
message
User-defined message. When the specified INT event occurs,
MXC-6300 matrix_dio remits this message. The message can
be of any value. In Windows, the message can be set to a
value including any Windows predefined messages, such as
WM_PAINT. However, to define a designated message, any
value ranging from WM_USER (0x400) to 0x7fff can be used.
This range is reserved by Windows for user-defined messages.
callbackAddr
Address of the user callback function. The MXC-6300
matrix_dio calls this function when the specified INT event
occurs. If no callback function is desired, set callbackAddr to 0.

DIO_INT1_EventMessage
