[JASS] What does Trigger synchronization do?

[spiwn]

When I tried to understand what the host finder script by PandaMine that it on this site does I saw the TriggerSyncStart() TriggerSyncReady() and SyncStoredInteger.
I wondered what they do.
And since I could not find an explanation I am asking:
What do they do?

Synching a Gamecache value makes it be the same (the host's value) on every computer.

I'm almost certain TriggerSyncStart and TriggerSyncReady are connected with the gamecache synching.

That explains it
P.s. They have to be, I believe before you synchronize you have to use TriggerSyncStart and when done TriggerSyncReady.

It does it to the one with the lowest lag/something, I do believe, or something like that - which may not be the host (normally is, but testing has shown it not to be perfect).
