This mime structure can be subsequently filled using the mime API, then attached to \fIeasy_handle\fP using option \fICURLOPT_MIMEPOST(3)\fP within a \fIcurl_easy_setopt(3)\fP call. 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 EXAMPLE .nf 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); .SH AVAILABILITY As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0. .SH RETURN VALUE A mime struct handle, or NULL upon failure. .SH "SEE ALSO" .BR curl_mime_addpart "(3)," .BR curl_mime_free "(3)," .BR CURLOPT_MIMEPOST "(3)"
