WIN32 DRIVERS FOR DIGITAL/VIDEO CAMCORDERS by Thomas Tewell    The only thing wrong with the emerging class of digital/video camcorders is the lack of software to use them. Consequently, Thomas wrote a complete IEEE 1394 class driver package for Windows 98 and his new Sony DCR-PC10 digital/video camcorder. Additional resources include win32dv.txt (listings) and win32dv.zip (source code).    資料來源:http://www.ddj.com/ 下載:http://www.ddj.com/ftp/1999/1999_06/win32dv.zip    Table 1:     REQUEST_ASYNC_READ   REQUEST_ASYNC_WRITE REQUEST_ASYNC_LOCK   REQUEST_ISOCH_ALLOCATE_BANDWIDTH REQUEST_ISOCH_ALLOCATE_CHANNEL   REQUEST_ISOCH_ALLOCATE_RESOURCES REQUEST_ISOCH_ATTACH_BUFFERS   REQUEST_ISOCH_DETACH_BUFFERS REQUEST_ISOCH_FREE_BANDWIDTH   REQUEST_ISOCH_FREE_CHANNEL REQUEST_ISOCH_FREE_RESOURCES   REQUEST_ISOCH_LISTEN REQUEST_ISOCH_STOP   REQUEST_ISOCH_TALK REQUEST_ISOCH_QUERY_CYCLE_TIME   REQUEST_ISOCH_QUERY_RESOURCES REQUEST_ISOCH_SET_CHANNEL_BANDWIDTH   REQUEST_ALLOCATE_ADDRESS_RANGE REQUEST_FREE_ADDRESS_RANGE   REQUEST_GET_LOCAL_HOST_INFO REQUEST_GET_ADDR_FROM_DEVICE_OBJECT   REQUEST_CONTROL REQUEST_GET_SPEED_BETWEEN_DEVICES   REQUEST_SET_DEVICE_XMIT_PROPERTIES REQUEST_GET_CONFIGURATION_INFO   REQUEST_BUS_RESET REQUEST_GET_GENERATION_COUNT   REQUEST_SEND_PHY_CONFIG_PACKET REQUEST_GET_SPEED_TOPOLOGY_MAPS   REQUEST_BUS_RESET_NOTIFICATION  REQUEST_ASYNC_STREAM   REQUEST_SET_LOCAL_HOST_PROPERTIES    Example 1:     Irb = ExAllocatePool(NonPagedPool, sizeof(IRB));  ...Fill out IRB for desired 1394 function...
