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(3) 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

RETURN VALUE
CURLE_OK or a CURL error code upon failure.
