This was done to SDL_DisplayMode for consistency with SDL_Surface and gives it a type so we don't have to do casts in SDL code.
I considered switching to an ID and hashing the driver data, etc. but all of that involved a lot of internal code churn and this solution gives us flexibility in how we handle this in the future.
After consideration, I made this renaming global across the project, for consistency.
Fixes https://github.com/libsdl-org/SDL/issues/10198
Any parameters (key/value pairs after the '?' in a URL) that have a keyname
that starts with `SDL_` will be put into Emscripten's environment variable
emulation table at startup, before SDL_main runs.
This lets users set hints the same way they might set them from a shell's
command line on a desktop platform:
For example:
`https://example.com/my_sdl3_application.html?SDL_RENDER_DRIVER=software`
Fixes#10154.
The new function includes the cursor position so IME UI elements can be placed relative to the cursor, as well as having the whole text area available so on-screen keyboards can avoid it.
SDL_StartTextInput(), SDL_StopTextInput(), SDL_TextInputActive(), SDL_ClearComposition(), and SDL_SetTextInputRect() all now take a window parameter.
This change also fixes IME candidate positioning when SDL_SetTextInputRect() is called before SDL_StartTextInput(), as is recommended in the documentation.
This declares that any `const char *` returned from SDL is owned by SDL, and
promises to be valid _at least_ until the next time the event queue runs, or
SDL_Quit() is called, even if the thing that owns the string gets destroyed
or changed before then.
This is noted in the headers as "the SDL_GetStringRule", so this will both be
greppable to find a detailed explaination in docs/README-strings.md and
wikiheaders will automatically turn it into a link we can point at the
appropriate documentation.
Fixes#9902.
(and several FIXMEs, both known and yet-undocumented.)
Otherwise, this will crash if the app sets its own SDL_malloc allocator, since
SDL_iconv uses SDL_malloc.
WideCharToMultibyte lets us calculate the needed memory for the argv[] string
conversions, and then we use the win32 HeapAlloc() API to get some memory
for it.
Fixes#8967.
Checking for the pipewire-pulse service is unreliable when used in containers such as Flatpak, so simply use a minimum version check instead and prefer it over the Pulseaudio backend if at least version 1.0.0.
Use DBus to query Systemd to check if the pipewire-pulse service is in the "running" state. If it is, then it is certain that Pipewire is being used instead of Pulseaudio as the preferred system mixer.
If DBus support is not enabled or Systemd is not being used on the underlying system, this check will simply fail and the standard driver order will be tested.
