Desc: When the app thinks there's data available for curl it calls this
function to read/write whatever there is right now. This returns
as soon as the reads and writes are done. This function does not
require that there actually is data available for reading or that
data can be written, it can be called just in case. It returns
the number of handles that still transfer data in the second
argument's integer-pointer.
CURLMcode type, general multi error code. *NOTE* that this only
returns errors etc regarding the whole multi stack. There might
still have occurred problems on invidual transfers even when this
returns OK.
