- * When defining this flag, you also need to:

+ *              (see the documentation of that option for context).
+ *
+ *              When you leave this undefined here, the library provides
+ *              a default definition. If the macro #MBEDTLS_CHECK_PARAMS_ASSERT
+ *              is defined, the default definition is `assert(cond)`,

+ *              `platform_util.h` for the benefit of the library, but
+ *              you need to define in your application.
+ *
+ *              When you define this here, this replaces the default
+ *              definition in platform_util.h (which no longer declares the
+ *              function mbedtls_param_failed()) and it is your responsibility

+ *              from within the library - you can ensure that by providing
+ *              them in this file next to the macro definition).
+ *              If you define this macro to call `assert`, also define
+ *              #MBEDTLS_CHECK_PARAMS_ASSERT so that library source files
+ *              include `<assert.h>`.
