Field Documentation

u_long _MCIFCB::fcb_blknum

Next block number to read. The file system driver will send a NUTBLKDEV_SEEK control command to set this value before calling the read or the write routine. The number is partition relative.

u_char _MCIFCB::fcb_blkbuf[MMC_BLOCK_SIZE]

Internal block buffer. A file system driver may use this one or optionally provide it's own buffers. Minimal systems may share their external bus interface with device I/O lines, in which case the buffer must be located in internal memory.
