Secure Digital Card Driver Structures (Windows CE 5.0)
The following table shows the secure digital (SD) card driver structures.
| Programming element | Description |
|---|---|
| SD_BUS_REQUEST | This structure contains information used to identify a bus request. This information is used to cancel or track a bus request. |
| SD_CARD_INTERFACE | This structure stores information on the physical nature of an SD card and its interface. |
| SD_COMMAND_RESPONSE | This structure stores the response from a card to a bus request. It contains information about the type of the response and the bytes that make up the response data. |
| SD_DATA_TRANSFER_CLOCKS | This structure is used to set data transfer clock timeouts of a device for read and write data transfers. This structure applies to the SD_SET_DATA_TRANSFER_CLOCKS card feature of the SDSetCardFeature function. |
| SD_HOST_BLOCK_CAPABILITY | This structure compares the block transfer capabilities of the host against a set of desired block transfer capabilities. The client driver should set the fields in this structure with the desired read and write block transfer parameters and check the values when the SDCardInfoQuery function returns. The query will update the block transfer parameters with values that closely match the desired parameters. The actual block transfer capabilities is host controller dependent. |
| SD_IO_FUNCTION_ENABLE_INFO | This structure contains information to control the enabling of an SDIO device function. This structure is used as a parameter to the SDSetCardFeature function. |
| SD_PARSED_REGISTER_CID | This structure contains the information obtained by parsing the CID register of an SD Memory card. |
| SD_PARSED_REGISTER_CSD | This structure contains all the information obtained by parsing the CSD register of an SD Memory card. |
| SDCARD_CLIENT_REGISTRATION_INFO | This structure is used to register a client name and a power callback routine during the client driver initialization sequence. |
| SDIO_CARD_INFO | This structure contains information describing the type and features of an SDIO card. |
