.TH curl_mime_headers 3 "January 02, 2023" "libcurl 7.88.1" "libcurl Manual"
.SH NAME
curl_mime_headers - set a mime part's custom headers
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_mime_headers(curl_mimepart *part,
struct curl_slist *headers, int take_ownership);
.fi
.SH DESCRIPTION
\fIcurl_mime_headers(3)\fP sets a mime part's custom headers.
\fIpart\fP is the part's handle to assign the custom headers list to.
\fIheaders\fP is the head of a list of custom headers; it may be set to NULL
to remove a previously attached custom header list.
\fItake_ownership\fP: 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.
.SH EXAMPLE
.nf
struct curl_slist *headers = NULL;
headers = curl_slist_append(headers, "Custom-Header: mooo");
/* use these headers, please take ownership */
curl_mime_headers(part, headers, TRUE);
/* pass on this data */
curl_mime_data(part, "12345679", CURL_ZERO_TERMINATED);
/* set name */
curl_mime_name(part, "numbers");
.fi
.SH AVAILABILITY
As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.
.SH RETURN VALUE
CURLE_OK or a CURL error code upon failure.
