Syntax

TCPREADHEADER socket

 

 

Remarks

This option is only available for the W5300 which includes a packet header with the packet size when align is set to 0.

TCP packets start with a 2 byte size header.

 

After you have read the TCP header, you can use TCPDATASIZE to read the number of bytes available in the packet.

TCPDATASIZE is a word variable you need to dimension yourself.

 

Socket is a constant or variable in the range from 0-7.
