下面的函數，是什么意思啊int _Cdecl access (const char *path, int amode);int _Cdecl _chmod (const char *path, int func, ... /* int attr */);int _Cdecl chmod (const char *path, int amode);int _Cdecl chsize (int handle, long size);int _Cdecl _close (int handle);int _Cdecl close (int handle);int _Cdecl _creat (const char *path, int attribute);int _Cdecl creat (const char *path, int amode);int _Cdecl creatnew (const char *path, int mode); /* DOS 3.0 or later */這幾個函數怎么看起來這么的復雜啊？？？
