Documentations in package:

SDL_GetMouseState - Query SDL’s cache for the synchronous mouse button state and the window-relative SDL-cursor position.

Defined in SDL3/SDL_mouse.h

#include "SDL3/SDL.h"

SDL_MouseButtonFlags SDL_GetMouseState(float *x, float *y);

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 .

	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.

( SDL_MouseButtonFlags ) Returns a 32-bit bitmask of the button state that can be bitwise-compared against the

SDL_BUTTON_MASK (X) macro.

This function should only be called on the main thread.

This function is available since SDL 3.2.0.
