CURLOPT_MIMEPOST - send data from mime structure
#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 email data to send/upload.
This option is the preferred way of posting an HTTP form,
replacing and extending the deprecated CURLOPT_HTTPPOST(3)
option.
Using this option implies the use of several mime structure building functions:
see https://curl.se/libcurl/c/smtp-mime.html for a complete example.
This will return CURLE_OK.
