Testing with no return type
The CURLOPT_PREREQFUNCTION callback must return either CURL_PREREQFUNC_OK or CURL_PREREQFUNC_ABORT

Testing with invalid value
The CURLOPT_PREREQFUNCTION callback must return either CURL_PREREQFUNC_OK or CURL_PREREQFUNC_ABORT

Testing with invalid option value
curl_setopt(): Argument #3 ($value) must be a valid callback for option CURLOPT_PREREQFUNCTION, no array or string given

Testing with invalid option callback
