Instance Method Details

#length ⇒ Object

The absolute length (in bytes) of the memory buffer. The memory is found from offset (inclusive) to offset + length (non-inclusive). When building messages using the encapsulated IPC message, padding bytes may be written after a buffer, but such padding bytes do not need to be accounted for in the size here.
