+:c:type:`uv_fs_poll_t` --- FS Poll handle
+=========================================
+
+FS Poll handles allow the user to monitor a given path for changes. Unlike
+:c:type:`uv_fs_event_t`, fs poll handles use `stat` to detect when a file has
+changed so they can work on file systems where fs event handles can't.
+
+
+Data types
+----------
+
+.. c:type:: uv_fs_poll_t
+
+    FS Poll handle type.
+
+.. c:type:: void (*uv_fs_poll_cb)(uv_fs_poll_t* handle, int status, const uv_stat_t* prev, const uv_stat_t* curr)
+
+    Callback passed to :c:func:`uv_fs_poll_start` which will be called repeatedly
+    after the handle is started, when any change happens to the monitored path.
+
+    The callback is invoked with `status < 0` if `path` does not exist
+    or is inaccessible. The watcher is *not* stopped but your callback is
+    not called again until something changes (e.g. when the file is created
+    or the error reason changes).
+
+    When `status == 0`, the callback receives pointers to the old and new
+    :c:type:`uv_stat_t` structs. They are valid for the duration of the
+    callback only.

+API
+---
+
+.. c:function:: int uv_fs_poll_init(uv_loop_t* loop, uv_fs_poll_t* handle)
+
+    Initialize the handle.
+
+.. c:function:: int uv_fs_poll_start(uv_fs_poll_t* handle, uv_fs_poll_cb poll_cb, const char* path, unsigned int interval)
+
+    Check the file at `path` for changes every `interval` milliseconds.
+
+    .. note::
+        For maximum portability, use multi-second intervals. Sub-second intervals will not detect
+        all changes on many file systems.
+
+.. c:function:: int uv_fs_poll_stop(uv_fs_poll_t* handle)
+
+    Stop the handle, the callback will no longer be called.
+
+.. c:function:: int uv_fs_poll_getpath(uv_fs_poll_t* handle, char* buffer, size_t* size)
+
+    Get the path being monitored by the handle. The buffer must be preallocated
+    by the user. Returns 0 on success or an error code < 0 in case of failure.
+    On success, `buffer` will contain the path and `size` its length. If the buffer
+    is not big enough `UV_ENOBUFS` will be returned and `size` will be set to
+    the required size.
+
+    .. versionchanged:: 1.3.0 the returned length no longer includes the terminating null byte,
+                        and the buffer is not null terminated.
+
+    .. versionchanged:: 1.9.0 the returned length includes the terminating null
+                        byte on `UV_ENOBUFS`, and the buffer is null terminated
+                        on success.
+
+
+.. seealso:: The :c:type:`uv_handle_t` API functions also apply.
