Syntax

class IFileCacheHandle

Remarks

All methods may be safely called from multiple threads simultaneously, unless otherwise noted

Also note, if you create several IFileCacheHandle's to the same file on separate threads these will be considered as individual separate files from the cache point of view and thus each will have their own cache data allocated.
