CGImageCreate providers invoking

I'm creating a cgimage with CGImageCreate() using the simple provider:

provider = ::CGDataProviderCreateWithData(NULL, data, <size>, NULL);

which I release after calling CGImageCreate()


What I can't seem to find adequate documentation for is:
Is the provider used (once only) during CGImageCreate?

If not I have to keep my data lying around, which is a pain, so I wonder if there's a way to flush it.

Or is the provider something that randomly might get called if the graphics card gets full and I has to re-load the bitmap or something?


Thanks,

Tor Langballe
