The structure message_context_t *ctp has a member info which
seems to have useful information, for example:
ctp->info.pid is the process id of the calling process.
There are two items ctp->info.nd (node?) and ctp->info.ndsrc (Node Source?) which I can’t find any documentation for.
When I send a message to a resource manager from the local node,
these are both zero. When I send a message across the network,
they are both the same value.
I’d like to know what the difference between them is, and if possible,
how to interpret them further.
Thanks for any assistance.
