Member Function Documentation

virtual size_t OpenDDS::DCPS::UdpSendStrategy::max_message_size

(

)

const [inline, protected, virtual]

The maximum size of a message allowed by the this TransportImpl, or 0 if there is no such limit. This is expected to be a constant, for example UDP/IPv4 can send messages of up to 65466 bytes. The transport framework will use the returned value (if > 0) to fragment larger messages. This fragmentation and reassembly will be transparent to the user.

Reimplemented from OpenDDS::DCPS::TransportSendStrategy.
