curl_mime_subparts(3)               libcurl              curl_mime_subparts(3)

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);

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

RETURN VALUE
       CURLE_OK or a CURL error code upon failure.
