SDL_GetGlobalMouseState - Man Page

#include <SDL3/SDL_mouse.h>

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

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.

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.

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.
