|

|
|
.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's 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.
|
||
|
|
