curl_mime_subparts - Man Page
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);
