It provides APIs for initializing the DDK, releasing the DDK, enabling and disabling devices, and reading data from and writing data to devices. It also declares the macros, enum variables, and data structures required by the SCSI Peripheral DDK APIs. 12 13**Since**: 18 14## Files 15 16| Name| Description| 17| -- | -- | 18| [scsi_peripheral_api.h](capi-scsi-peripheral-api-h.md) | Declares the SCSI Peripheral DDK APIs used by the host to access the SCSI device.| 19| [scsi_peripheral_types.h](capi-scsi-peripheral-types-h.md) | Provides the enum variables, structures, and macros used in the SCSI Peripheral DDK APIs.| 20
