Constructor & Destructor Documentation SdVolume::SdVolume ( void   )  [inline] Create an instance of SdVolume Member Function Documentation uint8_t SdVolume::blocksPerCluster ( void   )  [inline] Returns: The volume's cluster size in blocks. uint32_t SdVolume::blocksPerFat ( void   )  [inline] Returns: The number of blocks in one FAT. static uint8_t* SdVolume::cacheClear ( void   )  [inline, static] Clear the cache and returns a pointer to the cache. Used by the WaveRP recorder to do raw write to the SD card. Not for normal apps. uint32_t SdVolume::clusterCount ( void   )  [inline] Returns: The total number of clusters in the volume. uint8_t SdVolume::clusterSizeShift ( void   )  [inline] Returns: The shift count required to multiply by blocksPerCluster. uint32_t SdVolume::dataStartBlock ( void   )  [inline] Returns: The logical block number for the start of file data. uint8_t SdVolume::fatCount ( void   )  [inline] Returns: The number of FAT structures on the volume. uint32_t SdVolume::fatStartBlock ( void   )  [inline] Returns: The logical block number for the start of the first FAT. uint8_t SdVolume::fatType ( void   )  [inline] Returns: The FAT type of the volume. Values are 12, 16 or 32. uint8_t SdVolume::init ( Sd2Card &  dev, uint8_t  part   ) Initialize a FAT volume. Parameters: [in]  dev  The SD card where the volume is located. [in]  part  The partition to be used. Legal values for part are 1-4 to use the corresponding partition on a device formatted with a MBR, Master Boot Record, or zero if the device is formatted as a super floppy with the FAT boot sector in block zero. Returns: The value one, true, is returned for success and the value zero, false, is returned for failure. Reasons for failure include not finding a valid partition, not finding a valid FAT file system in the specified partition or an I/O error. uint8_t SdVolume::init ( Sd2Card &  dev  )  [inline] Initialize a FAT volume. Try partition one first then try super floppy format. Parameters: [in]  dev  The Sd2Card where the volume is located. Returns: The value one, true, is returned for success and the value zero, false, is returned for failure. Reasons for failure include not finding a valid partition, not finding a valid FAT file system or an I/O error. uint32_t SdVolume::rootDirEntryCount ( void   )  [inline] Returns: The number of entries in the root directory for FAT16 volumes. uint32_t SdVolume::rootDirStart ( void   )  [inline] Returns: The logical block number for the start of the root directory on FAT16 volumes or the first cluster number on FAT32 volumes. static Sd2Card* SdVolume::sdCard ( void   )  [inline, static] return a pointer to the Sd2Card object for this volume Friends And Related Function Documentation friend class SdFile [friend] Allow SdFile access to SdVolume private data.
