SYNTAX

#include <libowfat/cdb.h>
#include <libowfat/uint32.h>

int cdb_read(struct cdb *c, char *buf, size_t len, uint32 position);

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.

RETURN VALUE

cdb_read returns 0 if everything went well, or -1 on error (setting errno appropriately.
