.SH NAME
curl_mime_init \- create a mime handle
.SH SYNOPSIS
.nf
#include <curl/curl.h>

curl_mime *curl_mime_init(CURL *easy_handle);
.fi
.SH DESCRIPTION
\fIcurl_mime_init(3)\fP 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 \fICURLOPT_MIMEPOST(3)\fP within
a \fIcurl_easy_setopt(3)\fP call or added as a multipart in another mime
handle\(aqs part using \fIcurl_mime_subparts(3)\fP.

\fIeasy_handle\fP 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.
.SH EXAMPLE
.nf
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);
}
.fi
.SH AVAILABILITY
As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.
.SH RETURN VALUE
A mime struct handle, or NULL upon failure.
