2005-09-09 Tor Lillqvist <tml@novell.com> * gdk/win32/gdkdisplay-win32.c (gdk_display_get_name): Cache the display name. There is only one GdkDisplay on Win32, and constructing the display name isn't entirely trivial, so cacheing is probably worth it. For instance GIMP calls this function a lot. (gdk_display_open): Call gdk_display_get_name() to prime the cached name. (gdk_display_get_n_screens, gdk_display_get_screen, gdk_display_get_default_screen): Verify parameter correctness like the X11 backend does. * gdk/win32/gdkscreen-win32.c (gdk_screen_make_display_name): Return a freshly allocated string, as the API specifies. Fixes a heap corruption problem that caused random errors and crashes in GIMP, for instance.
