Expand description

Like try_read_message(), but does not allocate any memory. Stores the message in buffer. Returns a BufferNotLargeEnough error if the buffer is not large enough. ALIGNMENT: If the “unaligned” feature is enabled, then there are no alignment requirements on buffer. Otherwise, buffer must be 8-byte aligned (attempts to read the message will trigger errors).
