"it" being you deleting a file? No, that really cannot cause an exception. Can
you elaborate on what you're talking about?

The docs says:

         Passing a magic string "ALL" will erase all cookies known by cURL

That's not "a specific cookie". It means libcurl will erase all cookies from
its memory.

What would that accomplish? The docs explains how that option is used to pass
on a cookie header to the server and setting a NULL will then not send such an
extra header.

libcurl doesn't delete cookies from files at all. It can save all cookies it
knows about to a file so you'd have to erase the specific cookie from memory
first, then have libcurl save all of them.

Or you write your own code that can parse a cookie file and delete the
appropriate line.
