benstiglitz / EvilCast.h
Last active December 27, 2015 00:29
Safe bounded casting between types.
#if __has_extension(c_generic_selections) && __has_extension(c_static_assert)
#import "EvilCastImpl.h"
// Returns the value of s, clamping it to the bounds of type t. s and d must either both be integers
// or both be floating-point values.
#define EvilBoundedCheckedCast(t, s) __EvilChecked(t, s, Cast)
// Tries to assign the value of s to d, returning 1 if s is within the bounds of s and 0 if not.
// s and d must either both be integers or both be floating-point values.
#define EvilCheckedAssign(d, s) __EvilChecked(d, s, Assign)

Today’s bad shell script idea: netstrings.

((uintmax_t)1 << (sizeof(T) * 8)) - 1 : \
