+ *
+ * Allocates a Windows device context handle (HDC) for drawing into
+ * @drawable, and sets it up appropriately according to @usage.
+ *
+ * Each #GdkGC can at one time have only one HDC associated with it.
+ *
+ * The following flags in @mask are handled:
+ *
+ * If %GDK_GC_FOREGROUND is set in @mask, a solid brush of the
+ * foreground color in @gc is selected into the HDC. The text color of
+ * the HDC is also set. If the @drawable has a palette (256-color
+ * mode), the palette is selected and realized.
+ *
+ * If any of the line attribute flags (%GDK_GC_LINE_WIDTH,
+ * %GDK_GC_LINE_STYLE, %GDK_GC_CAP_STYLE and %GDK_GC_JOIN_STYLE) is
+ * set in @mask, a solid pen of the foreground color and appropriate
+ * width and stule is created and selected into the HDC. Note that the
+ * dash properties are not completely implemented.
+ *
+ * If the %GDK_GC_FONT flag is set, the background mix mode is set to
+ * %TRANSPARENT. and the text alignment is set to
+ * %TA_BASELINE|%TA_LEFT. Note that no font gets selected into the HDC
+ * by this function.
+ *
+ * Some things are done regardless of @mask: If the function in @gc is
+ * any other than %GDK_COPY, the raster operation of the HDC is
+ * set. If @gc has a clip mask, the clip region of the HDC is set.
+ *
+ * Note that the fill style, tile, stipple, and tile and stipple
+ * origins in the @gc are ignored by this function. (In general, tiles
+ * and stipples can't be implemented directly on Win32; you need to do
+ * multiple pass drawing and blitting to implement tiles or
+ * stipples. GDK does just that when you call the GDK drawing
+ * functions with a GC that asks for tiles or stipples.)
+ *
+ * When the HDC is no longer used, it should be released by calling
+ * <function>gdk_win32_hdc_release()</function> with the same
+ * parameters.
+ *
+ * If you modify the HDC by calling <function>SelectObject</function>
+ * you should undo those modifications before calling
+ * <function>gdk_win32_hdc_release()</function>.
+ *
+ * Return value: The HDC.
