Hi Dan, Thanks for the reply. I appreciate. Well My protocol is definitely on top of HTTPS. When I was using libcurl for the first time, I am able to send a GET request to a Server and then when server sends some message then my callback mentioned in writedata gets called, all this happens when I say curl_easy_perform().
the sequence that I want to generate is: 1) I will send a GET request to my server 2) Server will reply. 3) server can send asynchronous messages and I will have to read it. 4) I can also send asynchronous messages and reply to the messages coming from server. Now I am able to do till step3, but I am confused that once I prepare the response message of the message received from Server, how can I ask libcurl to read data from my read callback function. I believe I will have to do curl_easy_perform() again. Am I right here? I tried following: 1) once i get message from server in my write callback function I parsed it successfully. 2) now I want to prepare response message, which will be sent on top of HTTP GET and send to server, for that i want libcurl to read data from my read callback function, this is not happening now, what shall I do???? Please help me out in this, I appreciate the time you are puttting to help me.
