WebThe precise value also depends on the interface MTU. The interface MTU, in turn, may trigger IP fragmentation. In this case, the generated UDP-Lite packet is split into several IP packets, of which only the first one contains the L4 header. The send buffer size has implications on the checksum coverage length. Consider the following example: WebIP_OPTIONS may be used to provide IP options to be transmitted in the IP header of each outgoing packet or to examine the header options on incoming packets. IP options may be used with any socket type in the Internet family.
