Hi There,
I'm trying to tail a file in nodejs, the code is this:
var fs = require('fs');
var fName = 'file.txt';
fNameStat = fs.statSync(fName);
fs.watch(fName, function (evento, arquivo) {
fNameStatChanged = fs.statSync(arquivo);
console.log('file changed from ' + fNameStat.size + ' to ' +
fNameStatChanged.size);
fs.open(fName, 'r', function(err, fd) {
var newDataLength = fNameStatChanged.size - fNameStat.size;
console.log(newDataLength);
var buffer = new Buffer(newDataLength, 'utf-8');
console.log(buffer);
console.log(fd);
fs.read(fd, buffer, 0, newDataLength, null, function (err,
bytesRead, newData) {
if (err) {
console.log(err);
};
console.log(newData.toString());
});
fNameStat = fs.statSync(fName);
});
});
I'm getting this error:
fs.js:267
binding.read(fd, buffer, offset, length, position, wrapper);
^
Error: Offset is out of bounds
at Object.read (fs.js:267:11)
at Object.oncomplete (/var/www/read/test.js:13:15)
Anyone know whats happened?
