NAME

       curl_mime_subparts - set sub-parts of a multipart mime part

SYNOPSIS

       #include <curl/curl.h>

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

DESCRIPTION

       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 sub-parts. 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 multiple times 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.

EXAMPLE

        /* The inline part is an alternative proposing the html and the text
           versions of the email. */
        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);
