- * This is essentially a "wrapper" interface around standard C's IO

- * in the CRT" (http://msdn.microsoft.com/en-us/library/8ef0s5kh.aspx).
- * 2) But one of the greater reasons is for the possibility of large file
- * support in the future. I don't expect to reach the 2GB limit any
- * time soon (mainly because that would be insane). But when it comes
- * to adding support for some other larger IO tasks (in the test-suite,
- * or even the QCVM we'll need it). There is also a third possibility of
- * building .dat files directly from zip files (which would be very cool
- * at least I think so).
