This allows applications to re-query the values if the system locale is changed during runtime, and better matches the other locale functions. A note is included in the documentation mentioning that this can be slow, as it has to call into OS functions.
Also allows for the removal of the init/quit time functions, as they are no longer needed.
Queries the "panel orientation" property on the connector and reports it in degrees of clockwise rotation via the 'SDL.display.KMSDRM.panel_orientation' display property.
This is provided by the kernel as a hint to userspace applications, and the application itself is ultimately responsible for any required coordinate transformations needed to conform to the requested orientation.
This will provide a quick and easy way of clearing the error when a function succeeds, if we want to do that in a more widespread way.
For now we guarantee that SDL_Init() will never have an error set when it returns successfully.
Fixes https://github.com/libsdl-org/SDL/issues/8421
Added macros SDL_SINT64_C() and SDL_UINT64_C().
Integer suffixes of SDL_MAX_SINT64, SDL_MIN_SINT64, SDL_MAX_UINT64
and SDL_MIN_UINT64 are now system dependent.
The pointer confinement protocol does allow attempted warping the pointer via a hint, provided that the pointer is locked at the time of the request, and the requested coordinates fall within the bounds of the window.
Toggle the pointer locked state and request the pointer warp when the required protocol is available. This is similar to what XWayland does internally.
Any app for this system that wants to move to SDL3 will have to adjust to
all the other API changes anyhow, so there's no need to keep these anymore.
Fixes#9678.
- Adds support for modal windows to Win32, Mac, and Haiku, and enhances functionality on Wayland and X11, which previous set only the parent window, but not the modal state.
- Windows can be declared modal at creation time, and the modal state can be toggled at any time via SDL_SetWindowModalFor() (tested with UE5 through sdl2-compat).
- Allows dynamic unparenting/reparenting of windows.
- Includes a modal window test.
/ZW is incompatible with C++20, so disable the #error in that case. In addition, define a main function because UWP in C++20 mode links to standard main.
