这个源代码是我在没有参考任何现成的代码的情况下一个字母一个字母敲进去的.目前实现了创建文件,读写文件的操作,暂时不支持子目录、长文件名、文件删除、重命名等操作。 -This source code is what I refer to in the absence of any off-the-shelf code, one letter into a letter out. Realize the creation of the current document, read and write file operations, a temporary subdirectory does not support long file names, delete files, rename such operation.
