I have heard that ReadFile is better to use the _lread. Why is this? Are there any probmlems that may arrise if I use _lread? What are the advantages or disadvantages?

If I remember correctly, _lread calls ReadFile in the end. The ReadFile WriteFile CreateFile... functions are the native ones.

Well, in the end, all file handling functions call NtReadFile(), NtWriteFile(), and the other executive functions. So it probably doesn''t matter too much, except for a bit of indirection.

_lread is to ReadFile as _lseek is to?
