Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking, which may be 0, or 0 when end of stream is detected.

Usage

From source file:FileUtils.java

    int pos = 0;
    do {
        if (pos + avail > data.length) {
            byte[] newData = new byte[pos + avail];
            System.arraycopy(data, 0, newData, 0, pos);
