[Scummvm-devel] PORTERS: New OSystem API for loading/storing default config file

[Max Horn]

Hi there,


I just commited this patch. Thus, there are two new OSystem methods,  
which all porters may consider overloading:

   virtual Common::SeekableReadStream *openConfigFileForReading();
   virtual Common::WriteStream *openConfigFileForWriting();

The names should be pretty much self-explanatory, but if in doubt,  
check out the Doxygen docs in the header file, or at <http://doxygen.scummvm.org/ 
 >

The iPhone and PSP ports will probably be able to immediatly take some  
benefit from this, allowing the removal of some nasty hacks to get  
config file access right; other ports may be able to draw similar  
benefits. The goal is to eventually turn both methods into pure  
virtual ones, so please try to move your port specific code in common/ 
system.cpp to your port. In particular, these ports are affected:

* PalmOS
* iPhone
* PS2
* PSP
* Symbian
* SDL

I will move the SDL specific code there ASAP; this will require me to  
do the same for the Symbian port, though (which subclasses the SDL  
port), but I hope the Symbian folks won't mindy (I'll try to not cause  
breakage, and if I do it should be trivial to fix).


Cheers,
Max
