Very possible. In my previous experience of libcurl, all integral option values need to be cast to long in the curl_easy_setopt() function call. Here's what the manual (http://curl.haxx.se/libcurl/c/curl_easy_setopt.html) says: "curl_easy_setopt() is used to tell libcurl how to behave. By using the appropriate options to curl_easy_setopt, you can change libcurl's behavior. All options are set with the option followed by a parameter. That parameter can be a long, a function pointer, an object pointer or a curl_off_t, depending on what the specific option expects." It's very common for libcurl users to get into trouble by passing "1" when they mean "1L" or "(long)1". So common that the curl command itself may be guilty of the same mistake. -David -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
