[Ace-users] [ace-bugs] ACE : support all WindowsCE priorites withCeGetThreadPriority

[Steve Huston]

Hi Daniel,

This is a good idea - thank you for pointing it out. I don't believe
anyone is still supporting pre-5.0 CE, so this should be done.

Changing just the Get/SetPriority calls would be insufficient,
however, as there are other classes in ACE that deal with available
priority levels and their relationship. Could you please do one of the
following:

1. Enter this issue in Bugzilla so it doesn't get lost. If someone has
time to work on this and the integration and testing, the information
will be readily available.

2. Sponsor the correction of this feature. One way is to purchase ACE
support and then report it as broken.

Best regards,
-Steve

> As you can read on

> WindowsCE support 256 priority levels. But the ACE method
> ACE_OS::thr_getprio uses the legacy WindowsCE method 
> ::GetThreadPriority
> in order to retrieve the priority of current thread. So ACE 
> applications
> for WindowsCE can use 8 priority levels only. This is a big 
> problem for
> realtime based WindowsCE applications. If ACE would use
> ::CeGetThreadPriority instead of ::GetThreadPriority all 256 
> levels could
> be used.
