 For each error code defined in ESP-IDF components, :cpp:type:`esp_err_t` value can be converted to an error code name using :cpp:func:`esp_err_to_name` or :cpp:func:`esp_err_to_name_r` functions. For example, passing ``0x101`` to :cpp:func:`esp_err_to_name` will return "ESP_ERR_NO_MEM" string. Such strings can be used in log output to make it easier to understand which error has happened.
 
-Additionally, :cpp:func:`esp_err_to_name_r` function will attempt to interpret the error code as a `standard POSIX error code <http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/errno.h.html>`_, if no matching ``ESP_ERR_`` value is found. This is done using ``strerror_r`` function. POSIX error codes (such as ``ENOENT``, ``ENOMEM``) are defined in ``errno.h`` and are typically obtained from ``errno`` variable. In ESP-IDF this variable is thread-local: multiple FreeRTOS tasks have their own copies of ``errno``. Functions which set ``errno`` only modify its value for the task they run in.

 This feature is enabled by default, but can be disabled to reduce application binary size. See :ref:`CONFIG_ESP_ERR_TO_NAME_LOOKUP`. When this feature is disabled, :cpp:func:`esp_err_to_name` and :cpp:func:`esp_err_to_name_r` are still defined and can be called. In this case, :cpp:func:`esp_err_to_name` will return ``UNKNOWN ERROR``, and :cpp:func:`esp_err_to_name_r` will return ``Unknown error 0xXXXX(YYYYY)``, where ``0xXXXX`` and ``YYYYY`` are the hexadecimal and decimal representations of the error code, respectively.

     - A node can also use an IV Update procedure to signal to peer nodes that it is updating the IV Index.
     - The IV Update procedure is used to update the value of ESP-BLE-MESH network's IV Index. This value is related to the random number required for message encryption. To ensure that the value of the random number is not repeated, this value is periodically incremented. IV Index is a 32-bit value and a shared network resource. For example, all nodes in a mesh network share the same IV Index value. Starting from 0x00000000, the IV Index increments during the IV Update procedure and maintained by a specific process, ensuring the IV Index shared in the mesh network is the same. This can be done when the node believes that it has the risk of exhausting its sequence number, or when it determines that another node is nearly exhausting its sequence number. Note: The update time must not be less than 96 hours. It can be triggered when a secure network beacon is received, or when the node determines that its sequence number is greater than a certain value.

 错误代码并不直观，因此 ESP-IDF 还可以使用 :cpp:func:`esp_err_to_name` 或者 :cpp:func:`esp_err_to_name_r` 函数，将错误代码转换为具体的错误消息。例如，我们可以向 :cpp:func:`esp_err_to_name` 函数传递错误代码 ``0x101``，可以得到返回字符串 “ESP_ERR_NO_MEM”。这样一来，我们可以在日志中输出更加直观的错误消息，而不是简单的错误码，从而帮助研发人员更快理解发生了何种错误。
 
-此外，如果出现找不到匹配的 ``ESP_ERR_`` 值的情况，函数 :cpp:func:`esp_err_to_name_r` 则会尝试将错误码作为一种 `标准 POSIX 错误代码 <http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/errno.h.html>`_ 进行解释。具体过程为：POSIX 错误代码（例如 ``ENOENT``， ``ENOMEM``）定义在 ``errno.h`` 文件中，可以通过 ``errno`` 变量获得，进而调用 ``strerror_r`` 函数实现。在 ESP-IDF 中，``errno`` 是一个基于线程的局部变量，即每个 FreeRTOS 任务都有自己的 ``errno`` 副本，通过函数修改 ``errno`` 也只会作用于当前任务中的 ``errno`` 变量值。
+此外，如果出现找不到匹配的 ``ESP_ERR_`` 值的情况，函数 :cpp:func:`esp_err_to_name_r` 则会尝试将错误码作为一种 `标准 POSIX 错误代码 <https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/errno.h.html>`_ 进行解释。具体过程为：POSIX 错误代码（例如 ``ENOENT``， ``ENOMEM``）定义在 ``errno.h`` 文件中，可以通过 ``errno`` 变量获得，进而调用 ``strerror_r`` 函数实现。在 ESP-IDF 中，``errno`` 是一个基于线程的局部变量，即每个 FreeRTOS 任务都有自己的 ``errno`` 副本，通过函数修改 ``errno`` 也只会作用于当前任务中的 ``errno`` 变量值。
 
 该功能（即在无法匹配 ``ESP_ERR_`` 值时，尝试用标准 POSIX 解释错误码）默认启用。用户也可以禁用该功能，从而减小应用程序的二进制文件大小，详情可见 :ref:`CONFIG_ESP_ERR_TO_NAME_LOOKUP`。注意，该功能对禁用并不影响 :cpp:func:`esp_err_to_name` 和 :cpp:func:`esp_err_to_name_r` 函数的定义，用户仍可调用这两个函数转化错误码。在这种情况下， :cpp:func:`esp_err_to_name` 函数在遇到无法匹配错误码的情况会返回 ``UNKNOWN ERROR``，而 :cpp:func:`esp_err_to_name_r` 函数会返回 ``Unknown error 0xXXXX(YYYYY)``，其中 ``0xXXXX`` 和 ``YYYYY`` 分别代表错误代码的十六进制和十进制表示。
