NAME
SDL_GetGlobalMouseState - Query the platform for the asynchronous mouse button state and the desktop-
relative platform-cursor position.
SYNOPSIS
#include <SDL3/SDL_mouse.h>
SDL_MouseButtonFlags SDL_GetGlobalMouseState(float *x, float *y);
DESCRIPTION
This function immediately queries the platform for the most recent asynchronous state, more costly than
retrieving SDL's cached state in SDL_GetMouseState().
Passing non-NULL pointers to x or y will write the destination with respective x or y coordinates
relative to the desktop.
In Relative Mode, the platform-cursor's position usually contradicts the SDL-cursor's position as
manually calculated from SDL_GetMouseState() and SDL_GetWindowPosition.
This function can be useful if you need to track the mouse outside of a specific window and
SDL_CaptureMouse() doesn't fit your needs. For example, it could be useful if you need to track the mouse
while dragging a window, where coordinates relative to a window might not be in sync at all times.
FUNCTION PARAMETERS
x a pointer to receive the platform-cursor's x-position from the desktop's top left corner, can be
NULL if unused.
y a pointer to receive the platform-cursor's y-position from the desktop'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.
