This init call MUST have a corresponding call to \fIcurl_share_cleanup(3)\fP when all operations using the share are complete. This \fIshare handle\fP is what you pass to curl using the \fICURLOPT_SHARE(3)\fP option with \fIcurl_easy_setopt(3)\fP, to make that specific curl handle use the data in this share. .SH EXAMPLE .nf int main(void) { CURLSHcode sh; CURLSH *share = curl_share_init(); sh = curl_share_setopt(share, CURLSHOPT_SHARE, CURL_LOCK_DATA_CONNECT); if(sh) printf("Error: %s\\n", curl_share_strerror(sh)); } .fi .SH AVAILABILITY Added in 7.10 .SH RETURN VALUE If this function returns NULL, something went wrong (out of memory, etc.) and therefore the share object was not created. .SH "SEE ALSO" .BR curl_share_cleanup (3), .BR curl_share_setopt (3)
