+# NAME
+
+curl_mime_headers - set a mime part's custom headers
+
+# SYNOPSIS
+
+~~~c
+#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.

+
+# EXAMPLE
+
+~~~c
+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);
+}

+# %AVAILABILITY%
+
+# RETURN VALUE
+
+This function returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3). If CURLOPT_ERRORBUFFER(3) was set with curl_easy_setopt(3)
+there can be an error message stored in the error buffer when non-zero is
+returned.
