NAME

curl_mime_init - create a mime handle  

SYNOPSIS

#include <curl/curl.h>

curl_mime *curl_mime_init(CURL *easy_handle);

 

DESCRIPTION

curl_mime_init(3) creates a handle to a new empty mime structure. This mime structure can be subsequently filled using the mime API, then attached to some easy handle using option CURLOPT_MIMEPOST(3) within a curl_easy_setopt(3) call or added as a multipart in another mime handleaqs part using curl_mime_subparts(3).

easy_handle is used for part separator randomization and error reporting. Since 7.87.0, it does not need to be the final target handle.

Using a mime handle is the recommended way to post an HTTP form, format and send a multi-part email with SMTP or upload such an email to an IMAP server.  

PROTOCOLS

This functionality affects http, imap and smtp  

EXAMPLE

int main(void)
{
  CURL *easy = curl_easy_init();
  curl_mime *mime;
  curl_mimepart *part;

  /* Build an HTTP form with a single field named "data", */
  mime = curl_mime_init(easy);
  part = curl_mime_addpart(mime);
  curl_mime_data(part, "This is the field data", CURL_ZERO_TERMINATED);
  curl_mime_name(part, "data");

  /* Post and send it. */
  curl_easy_setopt(easy, CURLOPT_MIMEPOST, mime);
  curl_easy_setopt(easy, CURLOPT_URL, "https://example.com");
  curl_easy_perform(easy);

  /* Clea-up. */
  curl_easy_cleanup(easy);
  curl_mime_free(mime);
}

 

AVAILABILITY

Added in curl 7.56.0  

RETURN VALUE

A mime struct handle, or NULL upon failure.
