struct _ keyboard_input_data {
Ushort unitid;
Ushort makecode;
Ushort flags;
Ushort reserved;
Ulong extrainformation;
} Keyboard_input_data, * pkeyboard_input_data;
The sample program then cyclically traverses all the array members and obtains the key action from each member:
For (INT I = 0; I
{
Dbuplint ("scancode: % x \ n", keys [I]. makecode );
Note that you will receive two events: press the key and r
