fixstt

======

library to write/read fixed length status messages.

this library is developed to be used for `flaviodb `_

but can be used for any other purpose, flexibility isn't its strength :)

description

-----------

a fixstt entry contains the following fields:

* id:  64 bit integer, unique increasing id that identifies this message in this stream

* lat: 64 bit float, optional latitude  (double) set it to 9001 when no data

* lng: 64 bit float, optional longitude (double) set it to 9001 when no data

* date: 64 bit integer UTC unix timestamp in milliseconds when the record was created

* len: 16 bit integer, contains the length of the msg without padding

* ref: 64 bit integer, user defined meaning, for example can be used to store an id to extra data, or an offset in another file where extra data is stored

* type: 16 bit integer, can be used to define the msg type, payload content type etc

* msg: zero padded payload to fill the total msg size (default 512 bytes)
