UV_FS_READ:读取文件 uv_fs_read函数对应文件读取。不同于阻塞的文件读操作,这个函数可以无需等待文件读取完成,实现程序的其它操作同时进行。 UV_FS_WRITE:写入文件 与读操作类似,uv_fs_write函数支持异步地将数据写入到文件中。这提高了文件操作的性能,特别是在处理大型数据时。 UV_FS_CLOSE:关闭文件 完成文件...

I found this bug, that I originally reported on "luv" (Lua binding to libuv): luvit/luv#126 Basically, if you pass the fd returned from uv_fs_open() to uv_pipe_open(), then the first call to uv_read_start() will cause an abort(). Specifi...
