callback function to signal an unrecoverable error to the library and it will

Added in 7.21.5, the callback function may return

Pass a pointer that will be untouched by libcurl and passed as the first
argument in the sockopt callback set with \fICURLOPT_SOCKOPTFUNCTION\fP.

.IP CURLOPT_OPENSOCKETFUNCTION
Function pointer that should match the \fIcurl_opensocket_callback\fP
prototype found in \fI<curl/curl.h>\fP. This function gets called by libcurl
.IP CURLOPT_PROXYTYPE
Pass a long with this option to set type of the proxy. Available options for
this are \fICURLPROXY_HTTP\fP, \fICURLPROXY_HTTP_1_0\fP (added in 7.19.4),

the transfer type is set. The linked list should be a fully valid list of
struct curl_slist structs properly filled in as described for
