libuv provides a wide variety of cross-platform sync and async file system operations. All functions defined in this document take a callback, which is allowed to be NULL. If the callback is NULL the request is completed synchronously, otherwise it will be performed asynchronously.
All file operations are run on the threadpool. See threadpool for information on the threadpool size.
Note
On Windows uv_fs_* functions use utf-8 encoding.
The :cuv_req_t members also apply.
The :cuv_req_t API functions also apply.
