If an empty buffer is passed to rawRead, it throws.
This is a somewhat arbitrary limitation, and, in the generic case that the buffer a program may want to read would happen to have a length of 0, a needless corner case the programmer must be aware of. (I've had a long-running program crash half-way through because of this.)
Empty buffers are OK with the following:
- File.rawWrite
- fread
- Socket.send
- Socket.receive (although maybe this one shouldn't be, as its return value is then ambiguous).
