Current Index in Subkeyspace (skip + limit)

[Atticuss]

Hey guys. Working on a distributed wrapper for ocl/cudahashcat. I'd like to be able to post progress to the C2 server while running tasks. Is there any way to get the current index in the keyspace? Progress looks to use a different number so I seem to be left with estimating based on how long it's been executing. Suggestions?
