I just stumbled over some IOCTL codes, for which I could not find any
information:
0x182000 = CTL_CODE(FILE_DEVICE_PRINTER,0x0,METHOD_BUFFERED,FILE_ANY_ACCESS)
0x182008 = CTL_CODE(FILE_DEVICE_PRINTER,0x2,METHOD_BUFFERED,FILE_ANY_ACCESS)
0x182014 = CTL_CODE(FILE_DEVICE_PRINTER,0x5,METHOD_BUFFERED,FILE_ANY_ACCESS)
They look to be used together with printer/parport information querying like
IOCTL_PAR_QUERY_DEVICE_ID
Does anyone have any information on these codes?
Kind regards,
