# RETURN VALUE
CURLMcode type, general libcurl multi interface error code.
This function returns a CURLMcode indicating success or error.
CURLM_OK (0) means everything was OK, non-zero means an error occurred, see
libcurl-errors(3).
The return code is for the whole multi stack. Problems still might have
occurred on individual transfers even when one of these functions return OK.
