Packing
The Pack- and Unpack-functions are used to convert numbers->strings and strings->numbers. So you can read a binary file and then convert the received strings back to numbers and the other way around. Also you can use it in combination with the SendLuaXYZMsg-functions.
VFS.PackU8
VFS.PackU16
VFS.PackU32
VFS.PackS8
VFS.PackS16
VFS.PackS32
VFS.PackF32
arguments are:
VFS.PackX( number arg1, number arg2, number arg3, ... ) -> string
VFS.PackX( {[1]=number,[2]=number,..} ) -> string
VFS.UnpackU8
VFS.UnpackU16
VFS.UnpackU32
VFS.UnpackS8
VFS.UnpackS16
VFS.UnpackS32
VFS.UnpackF32
arguments are:
VFS.UnpackX( string "binary" [, number offset ] [, number count] )
-> number | table { [1]=number,[2]=number,.. }
