RIOSendEx get error 10022 but connect + RIOSend works well

It's an invalid argument and the main difference between the two calls is the address buffer.
I can't see anything obvious in your code but in mine I use sizeof(SOCKADDR_INET) as the variable you call ADDR_BUFFER_SIZE. This is 28 bytes for me. Seems like your 64 bytes shouldn't be a problem but it might be worth a try?

It get the same error 10022 at the same place, but thanks for your help

One more guess - in my code I allocate buffers for RIORegisterBuffer using VirtualAlloc with NULL as the first parameter:
PVOID buf = VirtualAlloc(NULL, bufferBytes, MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
This means that the buffers returned are page aligned. I don't remember having a problem but it is unlikely that I would have gone to the trouble without needing to...

I have try it, but still get error 10022
