gdigrab: Fix hwnd parameter issues
Converting from an integer to HWND (which is a pointer) requires an explicit cast, otherwise Clang errors out like this: src/libavdevice/gdigrab.c:280:14: error: incompatible integer to pointer conversion assigning to 'HWND' (aka 'struct HWND__ *') from 'long' [-Wint-conversion] 280 | hwnd = strtol(name, &p, 0); | ^ ~~~~~~~~~~~~~~~~~~~ (With GCC and MSVC, this was a mere warning, but with recent Clang, this is an error.) After adding a cast, all compilers also warn something like this: src/libavdevice/gdigrab.c:280:16: warning: cast to 'HWND' (aka 'struct HWND__ *') from smaller integer type 'long' [-Wint-to-pointer-cast] 280 | hwnd = (HWND) strtol(name, &p, 0); | ^~~~~~~~~~~~~~~~~~~~~~~~~~ On Windows, long types are 32 bit, so to get a usable pointer, we need to use long long. And interpret it as unsigned long long while at it - i.e. using strtoull. Finally, right above it, the code triggered the following warning: src/libavdevice/gdigrab.c:278:15: warning: mixing declarations and code is incompatible with standards before C99 [-Wdeclaration-after-statement] 278 | char *p; | ^ Signed-off-by: Martin Storsjö <martin@martin.st>
