 |
|
What would I use in place of IMPORT_FUNC?
Checked pspimport.s, it only lets you import functions...
EDIT 1:
======
Will using libsFindExportAddrByNid to find the real address and creating a pointer to it work?

As I understand it, you don't. Importing variables isn't supported right now. The way to handle that is to make accessor functions. If you have a variable called myDumbVar, access it by making functions like
| Code: | int GetMyDumbVar(void)
{
return myDumbVar;
}
void SetMyDumbVar(int val)
{
myDumbVar = val;
} |

I would definately do such basic things if it was my module.
but I was referring to FW modules like Vshmain, which happens to export one of its vars, which I am curious to play around with. |

but not supported in PSPSDK currently tho thats what he means
accesor functions is all you can do for now and there is no loss if you just inline the calls

oh! Hope to see some progress in future. Meanwhile,
[Q] Will that libsFind... func work? coz, it returns 0 as address.
[Q] And what did u mean by inline something?
Becz what u said wasnt clear. |

| As has been said a couple times now, you cannot import variables. It's just not in the SDK. For your OWN stuff, you use accessor functions and make them inline for no loss in speed (or very little loss). If you wish to add importing variables to the SDK, feel free. |

It isn't strictly a simple change to the SDK it requires slightly more complex changes to the actual toolchain. From what I recall an import entry for variables contains a list of fixups for the use in the code to point to the correct data. You might be able to get a lazy implementation by hard coding a single pointer reference but that is kinda nasty.
But yah feel free :P |

Last last thing. You dint actually say if it would work. [I reported that I got a 0 as the addr] [ but why? ]. I am afraid my effort is futile.
Let me know if it is suppozd to work. :)
Thanks. |

| Well libs find probably wont work without modification only because it probably doesn't look for variables :) You _should_ be able to write something which does what you want it to in theory using similar code. Never found any of the variables anything exports to be obviously useful :) |
