Yeah, I misunderstood the COOKIELIST option.

CURLOPT_COOKIELIST let's you add cookies to the in-memory cookie jar. It also 
offers some "commands" to manipulate that cookie jar. Not sure what you mean 
with "save", but maybe we mean the same thing?


You can read them as well, with the curl_easy_getinfo's corresponding 
CURLINFO_COOKIELIST option. Similar name, but that's for *reading* cookies.


which is why the program "froze", it just awaited input from the command 
line.


I don't understand how this option relates to any command line?

I still think that the documentation should use "" as the argument value or 
it should be stated that using "-" will require input (or CTRL + D).


"-" means libcurl will read from stdin instead of a file. It just seems it 
isn't mentioned in the CURLOPT_COOKIEFILE man page. I'll fix that right now.

Oh, I just realized that I misunderstood this. COOKIELIST works as
intended, it just save the cookies, not read them (I mixed the meanings
up), which is why the program "froze", it just awaited input from the
command line.

I still think that the documentation should use "" as the argument value or
it should be stated that using "-" will require input (or CTRL + D).
Thoughts?

CURLOPT_COOKIEFILE with "-" as filename freezes program

[Aron Bergman]

I'm trying to fetch cookies from a website and print them to the console.
To get started, I looked at the CURLINFO_COOKIELIST documentation
 and used the
example provided there.
The example states that you can enable the cookie engine using a
non-existing file and provides "-" as the filename argument on the line
below. Trying to run the example code  only make my program hang.
I then looked at the CURLOPT_COOKIEFILE documentation
 to see if there
were any clues to why this happened. The documentation states that:
"Given an empty or non-existing file or by passing the empty string ("") to
this option, you can enable the cookie engine without reading any initial
cookies."

Changed the argument from "-" to "" made the CURLINFO_COOKIELIST example
code work.
Are anyone having the same problem?
I suspect that the reason that the COOKIELIST example uses "-" is because
that would print to console using cURL on the commandline, but I don't know
if "-" is supposed to be supported in libcurl.

If the COOKIELIST example uses a unsupported argument I'll be happy to
create a PR.
