The share handle must have been 30created by a previous call to curl_share_init(3). Setting this option, 31makes this curl handle use the data from the shared handle instead of keeping 32the data to itself. This enables several curl handles to share data. If the 33curl handles are used simultaneously in multiple threads, you **MUST** use 34the locking methods in the share handle. See curl_share_setopt(3) for 35details. 36 37If you add a share that is set to share cookies, your easy handle uses that 38cookie cache and get the cookie engine enabled. If you stop sharing an object 39that was using cookies (or change to another object that does not share 40cookies), the easy handle gets its cookie engine disabled. 41 42Data that the share object is not set to share is dealt with the usual way, as 43if no share was used. 44 45Set this option to NULL again to stop using that share object. 46 47# DEFAULT 48 49NULL 50 51# %PROTOCOLS% 52 53# EXAMPLE 54 55~~~c 56int main(void) 57{ 58 CURL *curl = curl_easy_init(); 59 CURL *curl2 = curl_easy_init(); /* a second handle */ 60 if(curl) { 61 CURLcode res; 62 CURLSH *shobject = curl_share_init(); 63 curl_share_setopt(shobject, CURLSHOPT_SHARE, CURL_LOCK_DATA_COOKIE); 64 65 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); 66 curl_easy_setopt(curl, CURLOPT_COOKIEFILE, ""); 67 curl_easy_setopt(curl, CURLOPT_SHARE, shobject); 68 res = curl_easy_perform(curl); 69 curl_easy_cleanup(curl); 70 71 /* the second handle shares cookies from the first */ 72 curl_easy_setopt(curl2, CURLOPT_URL, "https://example.com/second"); 73 curl_easy_setopt(curl2, CURLOPT_COOKIEFILE, ""); 74 curl_easy_setopt(curl2, CURLOPT_SHARE, shobject); 75 res = curl_easy_perform(curl2); 76 curl_easy_cleanup(curl2); 77 78 curl_share_cleanup(shobject); 79 } 80} 81~~~ 82 83# %AVAILABILITY% 84 85# RETURN VALUE 86 87Returns CURLE_OK 88
