Usage

From source file:Main.java

public static void writeCString(OutputStream out, String s, String characterSet, int fixedLen)
        throws IOException {
    byte[] bytes = s.getBytes(characterSet);
    out.write(bytes.length);
    fixedLen -= 1;/*  w ww  . j  a v a 2 s .  com*/

    if (fixedLen <= 0)
        return;

    if (fixedLen <= bytes.length) {
        out.write(bytes, 0, fixedLen);
    } else {
        out.write(bytes);
        byte[] fillBytes = new byte[fixedLen - bytes.length];
        Arrays.fill(fillBytes, (byte) 0);
        out.write(fillBytes);
    }

    out.flush();
