# NAME
|
||
|
|
|
||
|
|
curl_mime_init - create a mime handle
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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.
|
||
|
|

curl_mime *mime;
|
||
|
|
curl_mimepart *part;
|

mime = curl_mime_init(easy);
|

|
|
part = curl_mime_addpart(mime);
|

|
curl_mime_name(part, "data");
|
