curl_mime_init(3) Library Functions 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. 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
handle's 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);
/* Clean-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.
