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); }
