Use GetObject() on an HFONT handle. Check the documentation for this. To
get the current font HFONT, if you've never actually selected one,
you'll probably find that GetStockObject() with a suitable parameter
does the job. Or perhaps the WM_GETFONT message will work.

Surely.

If you do, you'll get defaults for all the other values. This may or may
not be what you want.

BTW, it's often considered good practice to avoid memset() when it's not
necessary. In this case

 LOGFONT log_font = { 0 };
 log_font.lfHeight = font_height;
 log_font.lfWeight = FW_SEMIBOLD;
 log_font.lfEscapement = (LONG_T)(angle*10);

would do fine. On the other hand, given you've been asking about getting
the current font details, then something like (untested)

 LOGFONT log_font = { 0 };
 HFONT Font = reinterpret_cast<::SendMessage(hWnd, WM_GETFONT, 0, 0));
 GetObject(HFont, sizeof log_font, &log_font);
 log_font.lfEscapement = (LONG_T)(angle*10);

looks like the right way to go.
