EDT PDV digital imaging library.

| typedef struct edt_device* PdvDev |
PDV device handle, an opaque pointer.
For convenience, we use PdvDev in PDV applications, and EdtDev in applications for all other EDT applications. PdvDev and EdtDev are interchangable, some functions from edtlib can be called using a PdvDev handle.
| typedef enum edt_pdv_header_type EdtPdvHeaderType |
Definition for header data for buffers.
| typedef enum edt_pdv_header_position EdtPdvHeaderPosition |
Position of header relative to the bounds of a DMA buffer.
For disk I/O speed, header memory may be allocated with ring-buffer memory even if the header is not in the DMA stream. This covers all possible relationships of header memory to image data.
| typedef enum edt_pdv_serial_cmd_flag EdtPdvSerCmdFlag |
Serial command flags. Generally not used in application code.
| enum edt_pdv_header_type |
Position of header relative to the bounds of a DMA buffer.
For disk I/O speed, header memory may be allocated with ring-buffer memory even if the header is not in the DMA stream. This covers all possible relationships of header memory to image data.
