Vala FileUtils error

[days_of_ruin]

Heres the code:


using GLib;
using FileUtils;

public class FileReader : GLib.Object
{
string filename;
string content;
ulong len;

public FileReader(string filename)
{
this.filename = filename;
this.content = content;
this.len = len;

FileUtils.get_contents(filename,out content, out len);

}
}

public int main(string[] args)
{
var sample = new FileReader("filereader.vala");
return 0;
}


And heres the Error I get:

** (valac:17333): CRITICAL **: vala_scope_lookup: assertion `self != NULL' failed
filereader.c: In function ‘file_reader_construct’:
filereader.c:45: warning: passing argument 3 of ‘g_file_get_contents’ from incompatible pointer type


And here is the command I was compiling it with

valac -o filereader filereader.vala

Never mind.
The first error was from the "using FileUtils;"
the second error was because it wanted a uint instead of a ulong, not sure
why all the documentation uses ulong.
