[M3devel] Hard real time

[Jay K]

search the web for:
  "setthreadpriority"
  "opengroup sched.h"
http://www.opengroup.org/onlinepubs/007908799/xsh/sched.h.html
http://msdn.microsoft.com/en-us/library/ms686277(VS.85).aspx
etc.

 

 

Would be good to abstract out something that can be

done over pthreads and Win32 and possibly user threads.

 

 

As I understand, "hard real time" is rare.

You know, when page faults occur cannot be unpredictable

and still be hard real time, right?

 

 

"rough scheduling parameters", sure, but not "hard real time".

 

 

You could also ignore Win32 and user threads and

drop down into C and party on pthread_self().

 

 

That is, the key is coming up with portable interfaces

and interface "policing".
