NAME

curl_mime_headers - set a mime part's custom headers

SYNOPSIS

#include <curl/curl.h>
CURLcode curl_mime_headers(curl_mimepart *part,
struct curl_slist *headers, int take_ownership);

DESCRIPTION

curl_mime_headers(3) sets a mime part's custom headers. part is the part's handle to assign the custom headers list to. headers is the head of a list of custom headers; it may be set to NULL to remove a previously attached custom header list. take_ownership: when non-zero, causes the list to be freed upon replacement or mime structure deletion; in this case the list must not be freed explicitly. Setting a part's custom headers list multiple times is valid: only the value set by the last call is retained.

PROTOCOLS

This functionality affects http, imap and smtp

EXAMPLE

int main(void)
{
struct curl_slist *headers = NULL;
CURL *easy = curl_easy_init();
curl_mime *mime;
curl_mimepart *part;
headers = curl_slist_append(headers, "Custom-Header: mooo");
mime = curl_mime_init(easy);
part = curl_mime_addpart(mime);
/* use these headers in the part, takes ownership */
curl_mime_headers(part, headers, 1);
/* pass on this data */
curl_mime_data(part, "12345679", CURL_ZERO_TERMINATED);
/* set name */
curl_mime_name(part, "numbers");
/* Post and send it. */
curl_easy_setopt(easy, CURLOPT_MIMEPOST, mime);
curl_easy_setopt(easy, CURLOPT_URL, "https://example.com");
curl_easy_perform(easy);
}
