curl_mime_init - Man Page
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.
