curl_mime_init(3) libcurl Manual curl_mime_init(3)

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 intended to be used with easy_handle. This mime structure can be subsequently filled using the mime API, then attached to easy_handle using option CURLOPT_MIMEPOST(3) within a curl_easy_setopt(3) call.

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

AVAILABILITY

As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.

RETURN VALUE

A mime struct handle, or NULL upon failure.

EXAMPLE

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