SDL_PointInRectFloat(3) SDL3 FUNCTIONS SDL_PointInRectFloat(3)

SDL_PointInRectFloat - Determine whether a point resides inside a floating point rectangle.

Defined in SDL3/SDL_rect.h

#include "SDL3/SDL.h"
SDL_FORCE_INLINE bool SDL_PointInRectFloat(const SDL_FPoint *p, const SDL_FRect *r);

A point is considered part of a rectangle if both p and r are not NULL, and p and <= the rectangle's x+w and y+h. So a 1x1 rectangle considers point (0,0) and (0,1) as "inside" and (0,2) as not.

Note that this is a forced-inline function in a header, and not a public API function available in the SDL library (which is to say, the code is embedded in the calling program and the linker and dynamic loader will not be able to find this function inside SDL itself).

the point to test.
the rectangle to test.

Returns true if p is contained by r , false otherwise.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
