These minor changes remove portability issues with the this example and allow it to run on Win32. Specifically: * The use of pthread_create() has been replaced by g_thread_create(). This removes the dependency on the pthreads library. Since this is an example using GTK+, g_thread_create() is available as it is a part of glibc. * The CURLOPT_FILE option is now referred to by its "newer name" CURLOPT_WRITEDATA. * The use of CURLOPT_WRITEFUNCTION has been added. As described in the docs, this avoids the crashes when using a DLL under Win32. * The output file has been renamed from "/tmp/test.curl" to "test.curl". It's unlikely that there is a /tmp when in Win32 and other examples in libcurl write their output files to the working directory.
