TCP and UDS server in C# for KDB+
Hi All!
I am trying to build server for TCP and UDS in C# to which KDB+ can connect. CsharpKDB is only client. Is there any good description for messages that KDB processes exchange? How should these be structured? I can try to go through java code but I prefer to read some documentation if there is some.
Thank you!
Mr. J

You can find some details here:
Interprocess communication | Developing | kdb+ and q documentation – Kdb+ and q documentation (kx.com)

TCP/IP is used for communicating between processes. The protocol is extremely simple, as is the message format.

Additional question. Calling this:
h:hopen `::7000
(neg h)[“xx”]
Results in following message:
Byte representation
new byte[] { 1, 0, 0, 0, 16, 0, 0, 0, 10, 0, 2, 0, 0, 0, 120, 120, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, }
String representation:
xx
What does part 0, 0, 0, 10, 0, 2, 0, 0, 0 on positions 5 to 13 mean? What does it represent? Message should be with following attributes: LittleEndian: True, Compressed: False, Sync: False, Response: False.
Thank you.
