 * By default division is assumed to be usable if the type is present.
 * Uncomment this option to prevent the use of double-width division.
 *
 * Note that division for the native integer type is always required.
 * Furthermore, a 64-bit type is always required even on a 32-bit
 * platform, but it need not support multiplication or division. In some
 * cases it is also desirable to disable some double-width operations. For

/**
 * \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.

 * Uncomment to enable validation of application-controlled parameters.

/**
 * Uncomment the macro to let mbed TLS use your alternate implementation of
 * mbedtls_platform_zeroize(). This replaces the default implementation in
 * platform_util.c.
 *
 * mbedtls_platform_zeroize() is a widely used function across the library to
 * zero a block of memory. The implementation is expected to be secure in the
 * sense that it has been written to prevent the compiler from removing calls
 * to mbedtls_platform_zeroize() as part of redundant code elimination
 * optimizations. However, it is difficult to guarantee that calls to
 * mbedtls_platform_zeroize() will not be optimized by the compiler as older
 * versions of the C language standards do not provide a secure implementation
 * of memset(). Therefore, MBEDTLS_PLATFORM_ZEROIZE_ALT enables users to
 * configure their own implementation of mbedtls_platform_zeroize(), for
 * example by using directives specific to their compiler, features from newer
 * C standards (e.g using memset_s() in C11) or calling a secure memset() from
 * their system (e.g explicit_bzero() in BSD).

/**
 * Uncomment the macro to let Mbed TLS use your alternate implementation of
 * mbedtls_platform_gmtime_r(). This replaces the default implementation in
 * platform_util.c.
 *
 * gmtime() is not a thread-safe function as defined in the C standard. The
 * library will try to use safer implementations of this function, such as
 * gmtime_r() when available. However, if Mbed TLS cannot identify the target
 * system, the implementation of mbedtls_platform_gmtime_r() will default to
 * using the standard gmtime(). In this case, calls from the library to
 * gmtime() will be guarded by the global mutex mbedtls_threading_gmtime_mutex
 * if MBEDTLS_THREADING_C is enabled. We recommend that calls from outside the
 * library are also guarded with this mutex to avoid race conditions. However,
 * if the macro MBEDTLS_PLATFORM_GMTIME_R_ALT is defined, Mbed TLS will
 * unconditionally use the implementation for mbedtls_platform_gmtime_r()
 * supplied at compile time.
