- The "ALL" fake pathID is replaced by what does SM, having a public var NULL_STRING which will acts as NULL when needed. To make compiler accepting public array, this patch was needed: https://hg.alliedmods.net/sourcemod-central/rev/b12f329def09 - The offset thing in read_dir: considering that's something very specific to this native and that implementation in CDirectory doesn't make sense because of the offset compatibility for windows, all code is now in the native.
