Type | Description |
int | The size of the stream. |
read
Read bytes from the underlying buffer, retrying until we have read enough bytes or we cannot read any more. We do this because the internal C code for filling a buffer does not account for when we try to read large chunks from a user-land stream that does not return enough bytes.
