NAME
SDL_GetMouseState - Query SDL's cache for the synchronous mouse button state and the window-relative SDL-
cursor position.
SYNOPSIS
#include <SDL3/SDL_mouse.h>
SDL_MouseButtonFlags SDL_GetMouseState(float *x, float *y);
DESCRIPTION
This function returns the cached synchronous state as SDL understands it from the last pump of the event
queue.
To query the platform for immediate asynchronous state, use SDL_GetGlobalMouseState.
Passing non-NULL pointers to x or y will write the destination with respective x or y coordinates
relative to the focused window.
In Relative Mode, the SDL-cursor's position usually contradicts the platform-cursor's position as
manually calculated from SDL_GetGlobalMouseState() and SDL_GetWindowPosition.
FUNCTION PARAMETERS
x a pointer to receive the SDL-cursor's x-position from the focused window's top left corner, can be
NULL if unused.
y a pointer to receive the SDL-cursor's y-position from the focused window's top left corner, can be
NULL if unused.
RETURN VALUE
Returns a 32-bit bitmask of the button state that can be bitwise-compared against the SDL_BUTTON_MASK(X)
macro.
THREAD SAFETY
This function should only be called on the main thread.
AVAILABILITY
This function is available since SDL 3.2.0.
