+ * addition we'd like to give two layers of information on the error if

+ *
+ * For that purpose the error codes are segmented in the following manner:

+ * 16 bit error code bit-segmentation
+ *
+ * 1 bit  - Unused (sign bit)
+ * 3 bits - High level module ID
+ * 5 bits - Module-dependent error code
+ * 7 bits - Low level module errors
+ *
+ * For historical reasons, low-level error codes are divided in even and odd,
+ * even codes were assigned first, and -1 is reserved for other errors.

+ *        dynamically configured at runtime.
+ *
+ *        When all compilation options related to platform abstraction are
+ *        disabled, this header just defines `mbedtls_xxx` function names
+ *        as aliases to the standard `xxx` function.

+ *
+ * For other platforms, we provide an implementation that aims not to be
+ * optimized out by the compiler.
+ *
+ * This implementation for mbedtls_platform_zeroize() was inspired from Colin
+ * Percival's blog article at:
+ *
+ * http://www.daemonology.net/blog/2014-09-04-how-to-zero-a-buffer.html
+ *
+ * It uses a volatile function pointer to the standard memset(). Because the
+ * pointer is volatile the compiler expects it to change at
+ * any time and will not optimize out the call that could potentially perform
+ * other operations on the input buffer instead of just setting it to 0.
+ * Nevertheless, as pointed out by davidtgoldblatt on Hacker News
+ * (refer to http://www.daemonology.net/blog/2014-09-05-erratum.html for
+ * details), optimizations of the following form are still possible:
+ *
+ * if (memset_func != memset)
+ *     memset_func(buf, 0, len);
+ *
+ * Note that it is extremely difficult to guarantee that
+ * the memset() call will not be optimized out by aggressive compilers
+ * in a portable way. For this reason, Mbed TLS also provides the configuration
+ * option MBEDTLS_PLATFORM_ZEROIZE_ALT, which allows users to configure
+ * mbedtls_platform_zeroize() to use a suitable implementation for their
+ * platform and needs.
