'id_SwarmActivity_c', 'id_ScheduleIndex_c' and '_activity_swarmSyncType'?

[Philip Mötteli]

Hi


I have some problems, understanding the source code of Swarm. There's 
one variable in 'SwarmProcess.m', called '_activity_swarmSyncType'. 
This variable is declared as

        externvar id    _activity_swarmSyncType;

At least with this beast I found how it is declared, but I have no 
idea, where it gets its value. This is probably, because I couldn't 
find the definition of 'externvar'. It shouldn't be a global variable, 
because _activity_swarmSyncType is declared again in 'activity.m'.
So how does SwarmProcess get its value for _activity_swarmSyncType?

For the other two variables ('id_SwarmActivity_c' and 
'id_ScheduleIndex_c'), I couldn't even find a declaration and not to 
talk about, where and how they get initialized.

Could anybody help me except Marcus?


Thanks!
Phil
