So this code relies on fact there would be no exception in 'writeFile',
'fs.write' or any other called function. And if I try to change those, I
should keep in mind that sometimes I can throw exceptions and sometimes I
don't, like here:
if (!Buffer.isBuffer(buffer)) {
// legacy string interface (fd, data, position, encoding, callback)
callback = arguments[4];
position = arguments[2];
assertEncoding(arguments[3]);
buffer = new Buffer('' + arguments[1], arguments[3]);
offset = 0;
length = buffer.length;
}
assertEncding throws an error, but you just know that there would be a
buffer if it is called from 'writeAll'... Is that so?
