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 CURLOPT_HTTPPOST(3) option.

HTTP, SMTP, IMAP.


curl_mime *multipart = curl_mime_init(handle);
curl_mimepart *part = curl_mime_addpart(multipart);
curl_mime_name(part, "name");

part = curl_mime_addpart(multipart);
curl_mime_name(part, "project");
curl_mime_data(part, "curl", CURL_ZERO_TERMINATED);
part = curl_mime_addpart(multipart);
curl_mime_name(part, "logotype-image");
curl_mime_filedata(part, "curl.png");
/* Set the form info */
curl_easy_setopt(handle, CURLOPT_MIMEPOST, multipart);
curl_easy_perform(handle); /* post away! */
curl_mime_free(multipart); /* free the post data */
