SDL_RectsEqualEpsilon - Determine whether two floating point rectangles are equal, within some given
Contents
Availability
This function is available since SDL 3.2.0.
Description
Rectangles are considered equal if both are not NULL and each of their x, y, width and height are within
epsilon of each other. If you don't know what value to use for epsilon , you should call the
SDL_RectsEqualFloat
function instead.
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).
Function Parameters
a the first rectangle to test.
b the second rectangle to test.
epsilon
the epsilon value for comparison.
Header File
Defined in SDL3/SDL_rect.h
Name
SDL_RectsEqualEpsilon - Determine whether two floating point rectangles are equal, within some given
epsilon.
Return Value
