方法说明:

同步版的 lchmod()

语法:

复制代码 代码如下:

fs.lchmodSync(fd, mode)

由于该方法属于fs模块,使用前需要引入fs模块(var fs= require(“fs”) )

接收参数:

fd            文件描述符

mode          文件权限

源码:

复制代码 代码如下:

fs.lchmodSync = function(path, mode) {
    var fd = fs.openSync(path, constants.O_WRONLY | constants.O_SYMLINK);
    // prefer to return the chmod error, if one occurs,
    // but still try to close, and report closing errors if they occur.
    var err, err2;
    try {
      var ret = fs.fchmodSync(fd, mode);
    } catch (er) {
      err = er;
    }
    try {
      fs.closeSync(fd);
    } catch (er) {
      err2 = er;
    }
    if (err || err2) throw (err || err2);
    return ret;
  };
}
