This mime structure can be subsequently filled using the mime API, then attached to some easy handle using option \fICURLOPT_MIMEPOST(3)\fP within a \fIcurl_easy_setopt(3)\fP call or added as a multipart in another mime handle\(aqs part using \fIcurl_mime_subparts(3)\fP. \fIeasy_handle\fP is used for part separator randomization and error reporting. Since 7.87.0, it does not need to be the final target handle. Using a mime handle is the recommended way to post an HTTP form, format and send a multi\-part email with SMTP or upload such an email to an IMAP server. .SH PROTOCOLS This functionality affects http, imap and smtp .SH EXAMPLE .nf int main(void) { CURL *easy = curl_easy_init(); curl_mime *mime; curl_mimepart *part; /* Build an HTTP form with a single field named "data", */ mime = curl_mime_init(easy); part = curl_mime_addpart(mime); curl_mime_data(part, "This is the field data", CURL_ZERO_TERMINATED); curl_mime_name(part, "data"); /* Post and send it. */ curl_easy_setopt(easy, CURLOPT_MIMEPOST, mime); curl_easy_setopt(easy, CURLOPT_URL, "https://example.com"); curl_easy_perform(easy); /* Clean-up. */ curl_easy_cleanup(easy); curl_mime_free(mime); } .fi .SH AVAILABILITY Added in curl 7.56.0 .SH RETURN VALUE A mime struct handle, or NULL upon failure. .SH SEE ALSO .BR CURLOPT_MIMEPOST (3), .BR curl_mime_addpart (3), .BR curl_mime_free (3), .BR curl_mime_subparts (3)
