Usage

Reading a BARS File

using AalSharp.Bars;

byte[] data = File.ReadAllBytes("path/to/file.bars");
var bars = BarsFile.FromBinary(data, out var endianness);

Writing a BARS File

using AalSharp.Bars;

// Write to a stream
using FileStream fs = File.Create("path/to/output.bars");
bars.Write(fs, Endianness.Little);

// Write to a byte[]
byte[] data = bars.ToBinary(Endianness.Little, endianness: Entish.Endianness.Little);

Note

Writing to a pointer or Span<byte> can be done via the AalSharp.Bars.IO.BarsSerializer class
