CURLOPT_MIMEPOST man page

#include <curl/curl.h>

curl_mime *mime;

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MIMEPOST, mime);

Pass a mime handle previously obtained from curl_mime_init(3).

This setting is supported by the HTTP protocol to post forms and by the SMTP and IMAP protocols to provide the e-mail data to send/upload.

This option is the preferred way of posting an HTTP form, replacing and extending the deprecated CURLOPT_HTTPPOST(3) option.

HTTP, SMTP, IMAP.

Since 7.56.0.
