CURLOPT_COOKIEJAR(3)					     curl_easy_setopt options					      CURLOPT_COOKIEJAR(3)

NAME

       CURLOPT_COOKIEJAR - file name to store cookies to

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIEJAR, char *filename);

DESCRIPTION

       Pass  a	filename  as  char  *,	zero  terminated.  This  will  make  libcurl write all internally known cookies to the specified file when
       curl_easy_cleanup(3) is called. If no cookies are known, no file will be created. Specify "-" as filename to instead have the cookies writ-
       ten to stdout. Using this option also enables cookies for this session, so if you for example follow a location it will make matching cook-
       ies get sent accordingly.

       Note that libcurl doesn't read any cookies from the cookie jar. If you want to read cookies from a file, use CURLOPT_COOKIEFILE(3).

       If the cookie jar file can't be created or written to (when the curl_easy_cleanup(3) is called), libcurl will  not  and	cannot	report	an
       error  for  this. Using CURLOPT_VERBOSE(3) or CURLOPT_DEBUGFUNCTION(3) will get a warning to display, but that is the only visible feedback
       you get about this possibly lethal situation.

       Since 7.43.0 cookies that were 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.

DEFAULT

       NULL

PROTOCOLS

       HTTP

EXAMPLE

       TODO

AVAILABILITY

       Along with HTTP

RETURN VALUE

       Returns CURLE_OK if HTTP is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.

CURLOPT_ERRORBUFFER(3)					     curl_easy_setopt options					    CURLOPT_ERRORBUFFER(3)

NAME

       CURLOPT_ERRORBUFFER - set error buffer for error messages

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ERRORBUFFER, char *buf);

DESCRIPTION

       Pass  a	char  *  to a buffer that the libcurl may store human readable error messages in on failures or problems. This may be more helpful
       than just the return code from curl_easy_perform(3) and related functions. The buffer must be at least CURL_ERROR_SIZE bytes big.

       You must keep the associated buffer available until libcurl no longer needs it. Failing to do so will  cause  very  odd	behavior  or  even
       crashes. libcurl will need it until you call curl_easy_cleanup(3) or you set the same option again to use a different pointer.

       Consider CURLOPT_VERBOSE(3) and CURLOPT_DEBUGFUNCTION(3) to better debug and trace why errors happen.

       If the library does not return an error, the buffer may not have been touched. Do not rely on the contents in those cases.

DEFAULT

       NULL

PROTOCOLS

       All

EXAMPLE

       curl = curl_easy_init();
       if(curl) {
	 CURLcode res;
	 char errbuf[CURL_ERROR_SIZE];

	 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

	 /* provide a buffer to store errors in */
	 curl_easy_setopt(curl, CURLOPT_ERRORBUFFER, errbuf);

	 /* set the error buffer as empty before performing a request */
	 errbuf[0] = 0;

	 /* perform the request */
	 res = curl_easy_perform(curl);

	 /* if the request did not complete correctly, show the error
	 information. if no detailed error information was written to errbuf
	 show the more generic information from curl_easy_strerror instead.
	 */
	 if(res != CURLE_OK) {
	   size_t len = strlen(errbuf);
	   fprintf(stderr, "
libcurl: (%d) ", res);
	   if(len)
	     fprintf(stderr, "%s%s", errbuf,
		     ((errbuf[len - 1] != '
') ? "
" : ""));
	   else
	     fprintf(stderr, "%s
", curl_easy_strerror(res));
	 }
       }
