+/**
+ * \def MBEDTLS_CHECK_PARAMS
+ *
+ * This configuration option controls whether the library validates more of
+ * the parameters passed to it.
+ *
+ * When this flag is not defined, the library only attempts to validate an
+ * input parameter if: (1) they may come from the outside world (such as the
+ * network, the filesystem, etc.) or (2) not validating them could result in
+ * internal memory errors such as overflowing a buffer controlled by the
+ * library. On the other hand, it doesn't attempt to validate parameters whose
+ * values are fully controlled by the application (such as pointers).
+ *
+ * When this flag is defined, the library additionally attempts to validate
+ * parameters that are fully controlled by the application, and should always
+ * be valid if the application code is fully correct and trusted.
+ *
+ * For example, when a function accepts as input a pointer to a buffer that may
+ * contain untrusted data, and its documentation mentions that this pointer
+ * must not be NULL:
+ * - the pointer is checked to be non-NULL only if this option is enabled
+ * - the content of the buffer is always validated
+ *
+ * When this flag is defined, if a library function receives a parameter that
+ * is invalid, it will:
+ * - invoke the macro MBEDTLS_PARAM_FAILED() which by default expands to a
+ * call to the function mbedtls_param_failed()
+ * - immediately return (with a specific error code unless the function
+ * returns void and can't communicate an error).
+ *
+ * When defining this flag, you also need to:
+ * - either provide a definition of the function mbedtls_param_failed() in
+ * your application (see platform_util.h for its prototype) as the library
+ * calls that function, but does not provide a default definition for it,
+ * - or provide a different definition of the macro MBEDTLS_PARAM_FAILED()
+ * below if the above mechanism is not flexible enough to suit your needs.
+ * See the documentation of this macro later in this file.
+ *

+ * them in this file next to the macro definition).
