    Changes the current working directory.

.. c:function:: int uv_os_homedir(char* buffer, size_t* size)

    Gets the current user's home directory. On Windows, `uv_os_homedir()` first
    checks the `USERPROFILE` environment variable using
    `GetEnvironmentVariableW()`. If `USERPROFILE` is not set,
    `GetUserProfileDirectoryW()` is called. On all other operating systems,
    `uv_os_homedir()` first checks the `HOME` environment variable using
    :man:`getenv(3)`. If `HOME` is not set, :man:`getpwuid_r(3)` is called. The
    user's home directory is stored in `buffer`. When `uv_os_homedir()` is
    called, `size` indicates the maximum size of `buffer`. On success `size` is set
    to the string length of `buffer`. On `UV_ENOBUFS` failure `size` is set to the
    required length for `buffer`, including the null byte.

    .. warning::
        `uv_os_homedir()` is not thread safe.

    .. versionadded:: 1.6.0

    .. warning::
        `uv_os_tmpdir()` is not thread safe.

    .. versionadded:: 1.9.0

.. c:function:: int uv_os_get_passwd(uv_passwd_t* pwd)

    Gets a subset of the password file entry for the current effective uid (not
    the real uid). The populated data includes the username, euid, gid, shell,
    and home directory. On non-Windows systems, all data comes from
    :man:`getpwuid_r(3)`. On Windows, uid and gid are set to -1 and have no
    meaning, and shell is `NULL`. After successfully calling this function, the
    memory allocated to `pwd` needs to be freed with
    :c:func:`uv_os_free_passwd`.

    .. versionadded:: 1.9.0

.. c:function:: void uv_os_free_passwd(uv_passwd_t* pwd)

    Frees the `pwd` memory previously allocated with :c:func:`uv_os_get_passwd`.
