(iot_agent_datastore_t *datastore, void *dst, size_t offset, size_t *len)¶ Read from a datastore to a buffer in memory.
Starting at position
offset
,len
bytes are read from the datastore and copied to the memory pointed to bydst
.If the datastore does not hold
len
bytes or the read would be out of bounds, only as many bytes as available are read.len
is updated to hold the number of bytes that actually were read from the datastore.No length checks on
dst
are performed, the caller is responsible that the memory location is writeable and can holdlen
bytes.
