Pachube: how to upload 8 datastream at the same time?

Hello, I have some problem with pachube. I dont have space to use the official Pachube lib, so I have to write the code by myself. How update 8 datastream within the same PUT? The example in the new IDE are quite old. Any example code? Thank you

The following function doing it for me (but only for 3 datastreams).
You basically have to follow the notation :

0,
1,
2,
3,

7,

void WritePachube(void)
{
// update sensor feed
char PachubeData[64];

sprintf(PachubeData,
“0,%d.%d\n1,%d.%d\n2,%d\n”,
(int)FTemp[0], (int)((FTemp[0] - (int)FTemp[0]) * 100),
(int)FTemp[1], (int)((FTemp[1] - (int)FTemp[1]) * 100),
GetSuccessRate());

int nContentLength = strlen(PachubeData);

SerialPrint(“PUT request to update sensor feed… “);
LocalClient.print(“PUT /v2/feeds/”);
LocalClient.print(SENSOR_FEED_ID);
LocalClient.print(”.csv HTTP/1.1\n”);
LocalClient.print(“Host: api.pachube.com\n”);
LocalClient.print(“X-PachubeApiKey: “);
LocalClient.print(PACHUBE_API_KEY);
LocalClient.print(”\n”);
LocalClient.print(“Content-Type: text/csv\n”);
LocalClient.print(“Content-Length: “);
LocalClient.print(nContentLength);
LocalClient.print(”\n”);
LocalClient.print(“Connection: close\n\n”);
LocalClient.print(PachubeData);
LocalClient.print("\n");
LocalClient.print("\n");
SerialPrint(“done\n”);
}
