write a buffer
- Parameters
-
topic_ID buffer buffer to write: it must leave get_header_length() bytes free at the beginning. This will be filled with the header. length does not include get_header_length(). So buffer looks like this:
| header (leave free) | payload data |
| get_header_length() bytes | length bytes |
- Parameters
-
length buffer length excluding header length
- Returns
- length on success, <0 on error
