curl_mime_headers(3) libcurl 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 twice is valid: only the value set by the last call is retained.

AVAILABILITY

As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.

RETURN VALUE

CURLE_OK or a CURL error code upon failure.

EXAMPLE

 struct curl_slist *headers = NULL;
headers = curl_slist_append("Custom-Header: mooo", headers);
/* 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");
