[ft] question regarding use of volatile in Freetype

[JULIAN GARDNER]

I have ported freetype to a processor as part of a small test project and spent most of yesterday trying to find a crash in the system.

Went to bed with the problems and thought, check if Freetype is using volatile. The reason for this is that the embedded chip i am working on has a cache problem when using volatiles and these need to be handled in a certain way.

I did a grep and found volatiles used in numerous places, can someone please explain why they are being used, as i understand and have used in the past ..... years freetype should not need volatiles, there are no interrupt calls and no way in which data should be changed without a call into the freetype engine?
