.SH DESCRIPTION
|
2024-09-15 18:10:01 -06:00
|
|
|
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
|
2024-09-15 18:10:01 -06:00
|
|
|
\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.
|
2024-09-15 18:10:01 -06:00
|
|
|
|
|
|
|
Using this option multiple times makes the last set string override the
|
|
|
|
previous ones. Set it to NULL to disable its use again.
