The IOCTL_INTERNAL_I8042_MOUSE_WRITE_BUFFER request writes data to the i8042 port controller to control operation of a mouse device. An upper-level filter driver can use this request to control the operation of a mouse.
I8042prt synchronizes write buffer requests with one another. I8042prt synchronizes the actual write of data with the mouse ISR.
Parameters.DeviceIoControl.Type3InputBuffer points to a client-allocated buffer that supplies the data to write to an i8042 port controller.
Input Buffer Length
Parameters.DeviceIoControl.InputBufferLength is set to the number of bytes in the input buffer, which must be greater than 1.
Output Buffer Length
The Status member is set to one of the following values:
|Header||ntdd8042.h (include Ntdd8042.h)|
