curl_share_cleanup - Clean up a shared object
CURLSHcode curl_share_cleanup(CURLSH *share_handle);
This function deletes a shared object. The share handle cannot be used anymore
when this function has been called.
Passing in a NULL pointer in share_handle will make this
function return immediately with no action.
share = curl_share_init();
sh = curl_share_setopt(share, CURLSHOPT_SHARE, CURL_LOCK_DATA_CONNECT);
/* use the share, then ... */
CURLSHE_OK (zero) means that the option was set properly, non-zero means an
error occurred as <curl/curl.h> defines. See the
libcurl-errors.3 man page for the full list with descriptions. If an
error occurs, then the share object will not be deleted.
