NAME

       SDL_clamp - Return a value clamped to a range.

SYNOPSIS

       #include <SDL3/SDL_stdinc.h>

       #define SDL_clamp(x, a, b) (((x) < (a)) ? (a) : (((x) > (b)) ? (b) : (x)))

DESCRIPTION

       If  x  is  outside  the range a values between a and b, the returned value will be a or b as appropriate.
       Otherwise, x is returned.

       This macro will produce incorrect results if b is less than a.

       This is a helper macro that might be more clear than writing out the comparisons directly, and works with
       any type that can be compared  with  the  <  and  >  operators.  However,  it  double-evaluates  all  its
       parameters, so do not use expressions with side-effects here.

MACRO PARAMETERS

       x      the value to compare.

       a      the low end value.

       b      the high end value.

RETURN VALUE

       Returns x, clamped between a and b.

THREAD SAFETY

       It is safe to call this macro from any thread.
