Method description:
Change file permissions (not parsing symbolic links).
grammar:
The code copy is as follows:
fs.lchmod(fd, mode, [callback(err)])
Since this method belongs to the FS module, it is necessary to introduce the FS module before use (var fs= require("fs") )
Receive parameters:
fd file descriptor
mode file permissions
callback callback, passing exception parameter err
example:
The code copy is as follows:
fs.open('content.txt', 'a', function (err, fd) {
if (err) {
throw err;
}
fs.lchmod(fd, 0777, function(err){
if (err) {
throw err;
}
console.log('fchmod complete');
fs.close(fd, function () {
console.log('Done');
});
})
});
Source code:
The code copy is as follows:
fs.lchmod = function(path, mode, callback) {
callback = maybeCallback(callback);
fs.open(path, constants.O_WRONLY | constants.O_SYMLINK, function(err, fd) {
if (err) {
callback(err);
return;
}
// prefer to return the chmod error, if one occurs,
// but still try to close, and report closing errors if they occur.
fs.fchmod(fd, mode, function(err) {
fs.close(fd, function(err2) {
callback(err || err2);
});
});
});
};
