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.
