       #include <uint32.h>

       int cdb_read(struct cdb *c,char *buf,unsigned long int len,uint32 posi‐
       tion);

DESCRIPTION
       cdb_read reads len bytes starting at position from c to buf.   You  can
       use  cdb_datapos	 or  cdb_keypos	 to  get  position and cdb_datalen and
       cdb_keylen to get len.

       buf needs to point to a memory region large enough to hold len bytes.
