Title: Changing Symbian Process priority
Post by: Allstar12345 on November 30, 2013, 01:31:38 am

Here is how to change the process priority of your Symbian Application.

Libs required (for Qt usage):

Code: [Select]

-lavkon -leikcore- lcone
Includes:

Code: [Select]

#include <eikenv.h>
#include <eikappui.h>
#include <aknenv.h>
#include <aknappui.h>

Now the rest:

Code: [Select]

CEikonEnv::Static()->WsSession().ComputeMode(RWsSession::EPriorityControlDisabled);
    RProcess pMyApp;
    pMyApp.SetPriority(EPriorityHigh);
Obviously if you change the RProcess name from pMyApp remember to change it on the next line.

looks intresting :)
Will try it later, but I think not need all the headers and libaries are needed.

Probably won't need appui headers, they are for CaKnppUi.

exactly :P
and if you include a Avkon class (like aknappui.h) you don't have to include the related cone or uikon classes, because avkon itself already includes uikon and cone classes.

A easier way is to add this line in .pro file:

symbian:MMP_RULES += "EPOCPROCESSPRIORITY windowserver"

then you needn't add any code in .pro\.cpp

"windowserver" can be changed to background, foreground, high, windowserver, fileserver, realtimeserver or supervisor.

Is there any documentation about this so i can understand it more?
