.. c:function:: UV_ERRNO_MAP(iter_macro)

    Macro that expands to a series of invocations of `iter_macro` for
    each of the error constants above. `iter_macro` is invoked with two
    arguments: the name of the error constant without the `UV_` prefix,
    and the error message string literal.

.. c:function:: const char* uv_strerror(int err)

    Returns the error message for the given error code.  Leaks a few bytes
    of memory when you call it with an unknown error code.

.. c:function:: char* uv_strerror_r(int err, char* buf, size_t buflen)

    Returns the error message for the given error code. The zero-terminated
    message is stored in the user-supplied buffer `buf` of at most `buflen` bytes.

    .. versionadded:: 1.22.0

.. c:function:: const char* uv_err_name(int err)

    Returns the error name for the given error code.  Leaks a few bytes
    of memory when you call it with an unknown error code.

.. c:function:: char* uv_err_name_r(int err, char* buf, size_t buflen)

    Returns the error name for the given error code. The zero-terminated
    name is stored in the user-supplied buffer `buf` of at most `buflen` bytes.

    .. versionadded:: 1.22.0

.. c:function:: int uv_translate_sys_error(int sys_errno)

   Returns the libuv error code equivalent to the given platform dependent error
   code: POSIX error codes on Unix (the ones stored in `errno`), and Win32 error
   codes on Windows (those returned by `GetLastError()` or `WSAGetLastError()`).

   If `sys_errno` is already a libuv error, it is simply returned.

   .. versionchanged:: 1.10.0 function declared public.
