curl_share_cleanup - close a shared object

Added in curl 7.10

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 makes this function return immediately with no action. Any use of the share_handle after this function has been called and have returned, is illegal.

int main(void) { CURLSHcode sh; CURLSH *share = curl_share_init(); sh = curl_share_setopt(share, CURLSHOPT_SHARE, CURL_LOCK_DATA_CONNECT); /* use the share, then ... */ curl_share_cleanup(share); }

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 is not deleted.
