curl_mime_subparts(3) libcurl Manual curl_mime_subparts(3)
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 up-
dated 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 con-
tents 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
