The IOCTL Interface |
|
Applications software communicates with the CYUSB3.SYS driver primarily through the DeviceIoControl( ) function. (See the Windows SDK documentation for details about DeviceIoControl.)
Calls to DeviceIoControl require an IO Control (aka IOCTL) code parameter. The IOCTL codes define the programming interface that a driver supports and are particular to any given driver. The control code specified in a DeviceIoControl( ) call determines the values that must be specified for the other DeviceIoControl parameters.
This help file provides the IOCTL 'dictionary' for the CYUSB3.SYS driver.
Example
DWORD dwBytes = 0; UCHAR EndptAddress = 0x82;
DeviceIoControl(hDevice, IOCTL_ADAPT_RESET_PIPE, &EndptAddress, sizeof (EndptAddress), NULL, 0, &dwBytes, NULL);
