That does not work if _LARGEFILE64_SOURCE is not defined. In that case, the compiler

Sorry for that, I fixed and committed it.

The UDP connection you mention is only used locally for inter-process communication. When I implemented that, I
made extensive tests and found that there is never a packet being dropped. This happens for UDP only if the packet
goes over a physical network. Maybe this is different in modern Linux versions, so one should double check this

[quote="KO"]note 1: I do not completely understand the ss_suspend_xxx() stuff. The best I can tell is it creates a number of udp sockets bound to the local
host and at least one udp rpc receive socket ultimately connected to the cm_dispatch_rpc() function.[/quote]

 20 Jan 2009, Stefan Ritt, Info, Subrun scheme implemented
|
A new "subrun" scheme has been implemented in mlogger to split a big data file into several individual data files. This feature might be helpful if a data
file from a single run gets too large (>4 GB for example) and if shorter runs are not wanted for efficiency reasons. The scheme works as follows:

[quote="Renee Poutissou"]I have tested the new subrun functionality a bit more and I have two observations. First, it seems to work on a basic level, i.e.
subruns are created, which are equal in size. However, I can't relate their size to the byte limit set in the ODB.[/quote]
