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);


  }
}
