readAllOrException	`fun InputStream.readAllOrException(b: ByteArray): Int` Read bytes from the input stream into the array. If there are not enough bytes to fill the array, an exception is thrown.
readTwoBytesAsInt	`fun InputStream.readTwoBytesAsInt(): Int` Read the next two bytes from the InputStream, interpret them as a big-endian number (first byte most significant). This number is then returned.
skipAllOrException	`fun InputStream.skipAllOrException(n: UInt): UInt` Skip over `n` bytes. If there are only less than `n` bytes to skip over, an exception is thrown.
