Hello,

Is there a question or problem?

[aliceinwolderland]

i don't know how to do that, the program needs to ckeck if a certain message was sent and afterwards send an Open IGT Link update

[adamrankin]

Well, if your program is using sockets, then you'll have to check the return code from your send() function. Most of them will return an error code of timeout if the send did not complete.

Are you using igtl::ClientSocket as your client connection?

How do you want to send an update? Do you want to send an OpenIGTLink STATUS message?

[aliceinwolderland]

  Yes i'm using iglt::ClientSocket and yes i want to send an OpenIGTLink Status. For now i'm doing it in a endlessloop. But i want it to directly react to the sent message. So if there is a new message i want it to send an Open IGTLink Status.

Do you mean receiving a message? Or do you want to react to your own sending of messages?

igtl::Socket::Send(...) (parent of ClientSocket) wraps send(...)

If it returns with no error code, the data has been sent successfully.

@ningw-git The issue seems to be related to PlusServer, not OpenIGTLink. Can you post your question to https://github.com/PlusToolkit/PlusLib/issues ?
