NAME

       curl_mime_subparts - set subparts 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 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.

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);
