Standard library header <stdckdint.h> (C++26)

This header was originally in the C standard library (<stdckdint.h>).

This header is part of the numeric library, in particular, it provides several function templates for checked integer arithmetic.

It is unspecified whether <stdckdint.h> provides any declarations in namespace std.

Functions
ckd_add (C++26)	checked addition operation on two integers (function template)
ckd_sub (C++26)	checked subtraction operation on two integers (function template)
ckd_mul (C++26)	checked multiplication operation on two integers (function template)
