[sc-dev] win32 priority

["Victor Bombi" <sonoro@xxxxxxxxxxxxxx>]

Tim,

Reading  thread_priority_win32.hpp

SetPriorityClass is for the whole process (supernova is one process with 
several threads)
GetCurrentProcess() gives the supernova process
usually process priority is never touched and is left as 
NORMAL_PRIORITY_CLASS
thread priorities are based on the process priority
SetThreadPriority is for threads in the process
THREAD_PRIORITY_IDLE is veeeery low (-15)
THREAD_PRIORITY_NORMAL (0)
THREAD_PRIORITY_TIME_CRITICAL (15)

for the combined effect in base priority here is the reference
http://msdn.microsoft.com/en-us/library/windows/desktop/ms685100%28v=vs.85%29.aspx

I am not sure about the intentions of thread_set_priority and 
thread_set_priority_rt

I also dont understand:

int min, max;
boost::tie(min, max) = thread_priority_interval_rt();
int priority = max - 3;
priority = std::max(min, priority);

Best
victor
