oslib mem usage question

[hockeyhead019]

hey guys,

just curious to the method that oslib uses...

ok so when you load an image into the mem when does oslib take it out? like would you ever run into a problem if you (hypothetically speaking) loaded too much... and if so is there a simple function which would take it out of the memory?

thanks guys

Hey,
OSLib doesn't do any sort of memory management in the way of unloading stuff. If you load more than the RAM can hold you'll freeze the PSP.

oslDeleteSound();

and

oslDeleteImage();

Removes images/sounds from memory. You have to do them in a certain order though. If you load your images like this:

oslLoadImage(a, blah blah);
oslLoadImage(b, blah blah);
oslLoadImage(c, blah blah);

you have to unload them the opposite way:

oslDeleteSound(c);
oslDeleteSound(b);
oslDeleteSound(a);

thanks blade punk

but just curious what would happen if you tried to take them out of memory in the wrong order? would it just remove something that you didn't want removed? in other words is there a consequence to doing this wrong?

Freezes I think. Can't remember why. I think its mentioned in the OSLib doc

I think that only refers to when images, that were copied, are deleted before the copies.
