Day 15

Casey decides to restrict File IO to 32 bit limits for file size (under 4 gigs). This is due to a limitation do the win32 API in how much it can read into a provided buffer to ReadFile by the size of DWORD (4-bytes). For the purposes of this engine and problably almost all applications this is alright.

IF somehow more is needed, just reading in chunks of 4 gigs at a time is fine.

I ended up watching a vod earlier recommended: Mysteries of Memory Management Revealed,with Mark Russinovich Part 1 Part 2

Was really nice, I got some of the equivalent info for linux.
