Environment Variables

Hi All,

I need to understand following three environment variables and their usages in HP Unix.


_M_ARENA_OPTS
_M_CACHE_OPTS
PTHREAD_SCOPE_SYSTEM

How does these environment variables influence multi threaded applciation and how do we decide the value of these variables? Is there any relation between number of threads of the application and the values assigned to the variables?

Thanks
