12
14 curl_mime_init(3) creates a handle to a new empty mime structure. This
15 mime structure can be subsequently filled using the mime API, then at‐
16 tached to some easy handle using option CURLOPT_MIMEPOST(3) within a
17 curl_easy_setopt(3) call or added as a multipart in another mime han‐
18 dle's part using curl_mime_subparts(3).
19
20 easy_handle is used for part separator randomization and error report‐
21 ing. Since 7.87.0, it does not need to be the final target handle.
22
23 Using a mime handle is the recommended way to post an HTTP form, format
24 and send a multi-part email with SMTP or upload such an email to an
25 IMAP server.
