方法说明:
更改文件权限(文件描述符)。
语法:
fs.fchmod(fd, mode, [callback(err)])
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
callback 回调,传递异常参数err
例子:
fs.open('content.txt', 'a', function (err, fd) {
if (err) {
throw err;
}
fs.fchmod(fd, 0777, function(err){
if (err) {
throw err;
}
console.log('fchmod complete');
fs.close(fd, function () {
console.log('Done');
});
})
});
源码:
fs.fchmod = function(fd, mode, callback) {
binding.fchmod(fd, modeNum(mode), makeCallback(callback));
};
