Asyncronous WinHttp

Hi all.

I'm not used with windows programming at all to begin with. I'm more used with curl. However. I got to use Windows API this time, and I'm trying to get a hang of WinHttp but obviously get something wrong.

I wrote a little piece of code to go through the logic I need, but it segfaults. Can someone be so nice and point out where I'm going wrong?

Code:

#include <stdio.h> #include <assert.h> #include <stdlib.h> #include <windows.h> #include <winhttp.h> void http_callback(HINTERNET sess, DWORD_PTR ctx, DWORD sts, LPVOID info, DWORD infosz) { printf("Status: 0x%08x\n", sts); fflush(stdout); } int main(int argc, char **argv) { int r; HINTERNET sess; HINTERNET conn; HINTERNET requ; sess = WinHttpOpen( L"winhttp-test", WINHTTP_ACCESS_TYPE_DEFAULT_PROXY, WINHTTP_NO_PROXY_NAME, WINHTTP_NO_PROXY_BYPASS, WINHTTP_FLAG_ASYNC); assert(sess); r = (int) WinHttpSetStatusCallback( sess, (WINHTTP_STATUS_CALLBACK) http_callback, WINHTTP_CALLBACK_FLAG_ALL_NOTIFICATIONS, 0); assert(r != -1); conn = WinHttpConnect( sess, L"www.google.com", INTERNET_DEFAULT_HTTPS_PORT, 0); assert(conn); requ = WinHttpOpenRequest( conn, L"GET", L"/index.html", NULL, WINHTTP_NO_REFERER, WINHTTP_DEFAULT_ACCEPT_TYPES, WINHTTP_FLAG_SECURE); assert(requ); r = WinHttpSendRequest( requ, WINHTTP_NO_ADDITIONAL_HEADERS, 0, NULL, 0, 0, 0); assert(r); printf("Request sent!\n"); Sleep(10000); return EXIT_SUCCESS; }

The output of this program simply gets...

Code:

Status: 0x00000400

...and then it crashes.

Thanks.
