CURLSHOPT_UNSHARE - Man Page

#include <curl/curl.h>

CURLSHcode curl_share_setopt(CURLSH *share, CURLSHOPT_UNSHARE, long type);

The type parameter specifies what specific data that should no longer be shared and kept in the share object that was created with curl_share_init(3). In other words, stop sharing that data in this shared object. The given type must be one of the values described below. You can set CURLSHOPT_UNSHARE(3) multiple times with different data arguments to remove multiple types from the shared object. Add data to share again with CURLSHOPT_SHARE(3).

CURL_LOCK_DATA_COOKIE

Cookie data is no longer shared across the easy handles using this shared object.

CURL_LOCK_DATA_DNS

Cached DNS hosts are no longer shared across the easy handles using this shared object.

CURL_LOCK_DATA_SSL_SESSION

SSL session IDs are no longer shared across the easy handles using this shared object.

CURL_LOCK_DATA_CONNECT

The connection cache is no longer shared.

CURL_LOCK_DATA_PSL

The Public Suffix List is no longer shared.
