Using `TcpSocketBuilder` and then the created `ByteReadChannel`, how do I read a `UInt`?

so ByteReadChannel has a `readInt()` member function <https://api.ktor.io/ktor-io/io.ktor.utils.io/-byte-read-channel/index.html#598794336%2FFunctions%2F599479352>, but no `readUInt()` member or extension function

And so, at a guess, you could try reading the number of bytes required <https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-u-int/-s-i-z-e_-b-y-t-e-s.html|UInt.SIZE_BYTES> and then <https://stackoverflow.com/questions/53929025/how-to-get-an-unsigned-integer-from-a-byte-array-in-kotlin-jvm|convert them into a UInt>

Thanks! I guess the second solution would be simpler, I just don't want to mess with the binary representation

I need those unsigned ints to extract flags, bit by bit

```channel.readInt().toUInt()```
ahh yeah, if that works :+1:. I assumed it wouldn’t because `UInt.MAX_VALUE` is of course larger than `Int.MAX_VALUE` - but I guess the byte representation is the same

Follow up question: there doesn't seem to be an easy to use method to read an arbitrary amount of bytes into a byte array or buffer. Or maybe I can't find it

another option for UInt, you could do `readPacket(UInt.SIZE_BYTES)` <https://api.ktor.io/ktor-io/io.ktor.utils.io/-byte-read-channel/read-packet.html> which returns a <https://api.ktor.io/ktor-io/io.ktor.utils.io.core/-byte-read-packet/index.html|ByteReadPacket>, which has a <https://api.ktor.io/ktor-io/io.ktor.utils.io.core/-byte-read-packet/index.html#-1368578261%2FExtensions%2F-1955460546|readUInt()> extension

Is readPacket the most generic function to read n bytes?

There is also `readFully` which accepts a buffer/byte array.
Not sure what's the difference

I made it work correctly with `readPacket`. Thanks both!

Now I'd like to perform a write. Is there a way to concatenate two `ByteReadPacket` into a single `ByteReadPacket`? I need to perform an "atomic" write

Solved with the following code, which uses another builder
```sendChannel.writePacket {
  if (serializable.autosize()) {
    writeUInt(outputStream.getWrittenBytes().toUInt())
  }

  writePacket(payloadBuilder.build())
}```
