Network Packets in Detail MySQL

The communication protocol between the master and slave is the one that all other normal connections use, as described earlier in this document. See Chapter 8, MySQL Client/Server Protocol. So after the COM_BINLOG_DUMP command has been sent, the communication between the master and slave is a sequence of pa an example: net_safe_read() is called; it is able to detect wrong packets. After net_safe_read(), the event is ready to be interpreted; it starts at pointer (char*) mysql- >net.read_pos + 1. That is, (char*) mysql->net.read_pos + 1 is the first byte of the event's timestamp, etc.
