Hi guys,

I have a problem in code now.
*What I want is that*:
1. I will do GET to the server and wait for the response, it maybe waiting
for a long time.
2. I will do GET as a "Ping" to the server with another url for every 5 min.
3. I will do some POST to the server with another url as the command(it
will upload a audio file). In my mind, I think that maybe I can use the
"Ping" and the POST in one curl_handle, use the GET of waiting for response
in another curl_handle by multi API.
*So I do three test:*
1. I create two curl_handles, one for "Ping", the other for GET. This works
well. Every 5 min it will send the "Ping" again and the other handle is
waiting for the response. And the "Ping" can re-use.
2. Creating 2 curl_handles, one for POST, the other for GET. It seems work
well too, I input a command to POST again and again, this can work, but
seems no re-use.
3. Creating 2 curl_handles, one for POST and "ping", one for GET. It
couldn't work well now. In my code, first I send the PING and GET. And the
server can return the result. In this time, GET is still waiting and the
PING is finished. Then I input a command to let the curl_handle of "PING"
change to POST's configuration to do POST, but the error is occurred. The
POST can't send the file(a audio file).
*My question is:*
If I use the curl in a wrong way?
Can I use the PING and POST in the same curl_handle and re-use it?
Please give me some suggestion.
I used the libcurl7.51.0

*This is my code:*
