Hi Brandon,
Thanks, I just pushed in those changes in the information
in comments. if you see other examples like that, please do
tell me about them, and I'll fix them.
Best,

Subject: Re: [Dmtcp-forum] dmtcp aware question
Thanks Gene - I think my primary issue was compiling without -fPIC.
Good to know about the new status #defines as well.
Some notes in the applic.c files seem to be potentially off: for
instance, the comment has 'dmtcpGetLocalStatus' but I believe it
should be 'dmtcp_get_local_status'.
