It should be * used for debugging purposes only to check for conditions that should never * occur. This macro can be disabled in release builds by defining NDEBUG and * should not be used for error handling. * * The mp_require macro is similar to mp_assert but more strict. It enforces * critical assertions even in release builds. If the condition is not met, this * macro will abort the program, making it suitable for error handling in cases * where recovery is impossible. Note that this macro does not log any messages * to keep as small footprint as possible in NDEBUG builds. */ #ifndef NDEBUG #include <assert.h> #define mp_assert assert#define mp_require assert #else #include <stdio.h>#include <stdlib.h> #define mp_require(expr)                                       \    do {                                                       \        if (!(expr))                                           \            abort();                                           \    } while (0) #define mp_assert(expr) do { (void)sizeof(expr); } while (0) #endif
