- * Uncomment to provide your own alternate implementation for mbedtls_platform_fault(),

- * mbedtls_platform_memcpy, mbedtls_platform_memset or mbedtls_platform_random_buf.
+ * Uncomment to provide your own alternate implementation for

  * You will need to provide a header "platform_fault.h" and an implementation at
  * compile time.
