locks in threads

[Markus von Ehr]

Hi,

I have an one thread running. The user constructs the data (read and
write)
in a complicated class structure and the thread (running every 100 ms)
only has to read this data. Are there any problems (program crash etc.)
when I don't use variable locks? The thread only has to read integers
out
of the data structure. I don't care if I read an older or a newer value.

Thanx a lot,

Markus
