Code: Select all    int size;
    while ((size = client.available()) > 0) {
      uint8_t* msg = (uint8_t*)malloc(size);
      size = client.read(msg, size);
      Serial.write(msg, size);
      free(msg);
    }

Specifically what malloc do?

P.S I am logging temperature successful for 8 h now

- Fri May 27, 2016 7:03 am #48108 The above code simply print the whole response from the client, what ever the size of it, either few bytes or several kilobytes, by reading it chunk by chunk while it been received. The malloc() allocates temporary memory buffer to the size of the chunk and free it as soon it has been outputted to the Serial before processing next chunk.
