Hi everybody.
I am new to device driver. I am trying to create encrypted filter driver using minifilter. However, I am confusing context definition in mini-filter. I’ve search a lot but I can not find a clear definition. I know in minifilter, there are a lot of contexts such as: files, stream, streamhandler, volume,…etc but i dont know which situation use those contexts.
Can anybody define what context in minifilter is? Moreover, in swapbuffer source from DDK, why do they use volume context? if I encrypt file only, do I need to use streamhandle context or volume context?
if my question is not clear, please forgive me because english is not my mother language.
Thanks in advance
