CURLSHOPT_UNSHARE - remove data to share

Added in curl 7.10.3

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.

int main(void) { CURLSHcode sh; CURLSH *share = curl_share_init(); sh = curl_share_setopt(share, CURLSHOPT_UNSHARE, CURL_LOCK_DATA_COOKIE); if(sh) printf("Error: %s\n", curl_share_strerror(sh)); }
