/*
|
|
* These are the various messages that can be sent between the master
|
|
* and slave. The slave sends one reply to each message from the master.
|
|
|
|
* PING/PINGREPLY: just what it sounds like.
|
|
|
|
* STARTTASK: starts a task. Needs to be reworked to allow code
|
|
* shipping. The slave attempts to perform the task, and replies with
|
|
* FINISHEDTASK or TASKFAILED.
|
|
*
|
|
* RETRIEVELOCALFILE: requests a file that the slave has stored
|
|
* locally. Slave replies with SENDLOCALFILE and the file, or with
|
|
* LOCALFILENOTFOUND.
|
|
*
|
|
* SHIPCODE: sends a shared library to the slave, containing a
|
|
* function that is to be executed later by the STARTTASK
|
|
* command. Slave replies with CODESAVED or SHIPFAILED.
