.TH curl_mime_headers 3 "22 August 2017" "libcurl" "libcurl"
|
|
.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.
|
|
