From the doc:

NOTE: If you're using libcurl as a win32 DLL, you MUST use the
CURLOPT_WRITEFUNCTION if you set this option or you will experience
crashes.

Has to do with the whole FILE* not being valid to pass accross dll/process
boundaries issues.....

Hello all,

Im using libCURL to query a website to see if new forum posts and private
messages exist for a certain user, and if so enabling a toolbar button.
The problem is its crashing when I use

FILE* f = fopen("C://foo.txt","w");
curl_easy_setopt(curl,CURLOPT_FILE ,f);

It actually crashes on the "setopt" call.  What gives ?  All i really want
to do is dump the info into a string to search it, any suggestions on how
to proceed ?

Im using libCURL 7.10.2, MSVC++ 6.0, and ATL and WTL to create the
Toolbar, which resides in a DLL and gets called upon IE startup.

Thanks,
Charles
