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(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¶
static char *inline_html = "<title>example</title>"; static char *inline_text = "once upon the time"; int main(void) {
CURL *curl = curl_easy_init();
if(curl) {
struct curl_slist *slist;
/* The inline part is an alternative proposing the html and the text
versions of the email. */
curl_mime *alt = curl_mime_init(curl);
curl_mimepart *part;
/* 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(alt);
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);
} }
