.TH CURLOPT_COOKIEJAR 3 "17 Jun 2014" libcurl libcurl
|
||
|
.SH NAME
|
||
|
CURLOPT_COOKIEJAR \- file name to store cookies to
|
||
|
.SH SYNOPSIS
|
||
|
.nf
|
||
|
#include <curl/curl.h>
|
||
|
|
||
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIEJAR, char *filename);
|
||
|
.fi
|
||
|
.SH DESCRIPTION
|
||
|
Pass a \fIfilename\fP as a char *, null-terminated. This makes libcurl write
|
||
|
all internally known cookies to the specified file when
|
||
|
\fIcurl_easy_cleanup(3)\fP is called. If no cookies are kept in memory at that
|
||
|
time, no file is created. Specify "-" as filename to instead have the cookies
|
||
|
written to stdout. Using this option also enables cookies for this session, so
|
||
|
if you for example follow a redirect it makes matching cookies get sent
|
||
|
accordingly.
|
||
|
|
||
|
Note that libcurl does not read any cookies from the cookie jar specified with
|
||
|
this option. To read cookies from a file, use \fICURLOPT_COOKIEFILE(3)\fP.
|
||
|
|
||
|
If the cookie jar file cannot be created or written to (when the
|
||
|
\fIcurl_easy_cleanup(3)\fP is called), libcurl does not and cannot report an
|
||
|
error for this. Using \fICURLOPT_VERBOSE(3)\fP or
|
||
|
\fICURLOPT_DEBUGFUNCTION(3)\fP displays a warning, but that is the only
|
||
|
visible feedback you get about this possibly lethal situation.
|
||
|
|
||
|
Cookies are imported in the Set-Cookie format without a domain name are not
|
||
|
exported by this option.
|
||
|
|
||
|
The application does not have to keep the string around after setting this
|
||
|
option.
|
||
|
.SH DEFAULT
|
||
|
NULL
|
||
|
.SH PROTOCOLS
|
