curl_mime_subparts - set subparts of a multipart mime part

#include <curl/curl.h>

CURLcode curl_mime_subparts(curl_mimepart * */part/,* curl_mime * */subparts/);*

curl_mime_subparts(3) sets a multipart mime part’s content from a mime structure.

part is a handle to the multipart part.

subparts is a mime structure handle holding the subparts. After curl_mime_subparts succeeds, the mime structure handle belongs to the multipart part and must not be freed explicitly. It may however be updated by subsequent calls to mime API functions.

Setting a part’s contents twice is valid: only the value set by the last call is retained. It is possible to unassign previous part’s contents by setting subparts to NULL.

   /* The inline part is an alternative proposing the html and the text
      versions of the e-mail. */
   alt = curl_mime_init(curl);

   /* HTML message. */
   part = curl_mime_addpart(alt);
   curl_mime_data(part, inline_html, CURL_ZERO_TERMINATED);
   curl_mime_type(part, "text/html");

   /* Text message. */
   part = curl_mime_addpart(alt);
   curl_mime_data(part, inline_text, CURL_ZERO_TERMINATED);

   /* Create the inline part. */
   part = curl_mime_addpart(mime);
   curl_mime_subparts(part, alt);
   curl_mime_type(part, "multipart/alternative");
   slist = curl_slist_append(NULL, "Content-Disposition: inline");
   curl_mime_headers(part, slist, 1);

As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.

CURLE_OK or a CURL error code upon failure.
