The following table shows the secure digital (SD) card driver structures.
| Programming element | Description |
|---|---|
This structure is used to set the host function power state. |
|
Applies to Windows Embedded CE 6.0 R2 This structure is used to define a physical address buffer and is an input structure for SDSynchronousBusRequestEx and SDBusRequestEx. The members of this structure should be set using the members of the SD_HOST_ALLOC_FREE_DMA_BUFFER structure. |
|
This structure contains information used to identify a bus request. This information is used to cancel or track a bus request. |
|
This structure stores information on the physical nature of an SD card and its interface. |
|
Applies to Windows Embedded CE 6.0 R2 This structure stores information on the physical nature of an SD card and its interface. |
|
Applies to Windows Embedded CE 6.0 R2 This structure is used to switch between card command mode and interface/high speed mode. |
|
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. |
|
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. |
|
Applies to Windows Embedded CE 6.0 R2 This structure is used to allocate and de-allocate a direct memory access (DMA) buffer from the SD host. This structure can only be used when the SD host controller driver supports DMA. SD_HOST_ALLOC_FREE_DMA_BUFFER is also used to define the PHYS_BUFF_LIST structure when making an SD bus request with SDBusRequestEx and SDSynchronousBusRequestEx. |
|
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 capability is host controller dependent. |
|
This structure contains information to control the enabling of an SDIO device function. This structure is used as a parameter to the SDSetCardFeature function. |
|
Applies to Windows Embedded CE 6.0 R2 This structure describes the physical interface to an SD card. |
|
This structure contains the information obtained by parsing the CID register of an SD Memory card. |
|
This structure contains all the information obtained by parsing the CSD register of an SD Memory card. |
|
This structure is used to register a client name and a power callback routine during the client driver initialization sequence. |
|
This structure contains information describing the type and features of an SDIO card. |
