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);
