curl_mime_headers(3) Library Functions Manual curl_mime_headers(3)
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);
