I suspect the question was asked somewhere before.
If so just give a link.
Anyway:
```d
class IoContext {
...
ubyte[] buf;
...
this(uint bufSize) {
buf = new ubyte[bufSize];
}
}
```
```d
class IoContext {
...
ubyte[] buf;
...
this(uint bufSize) {
buf.length = bufSize; //this should do the same thing, I
believe
}
}
```
The buffer contains (ascii) string terminated with '\n'.
In order to print it not as an array of numbers (buf is 1024
bytes long),
but as usual string I do
```d
char[] s = cast(char[])ioCtx.buf[0 ..
strlen(cast(char*)ioCtx.buf.ptr) - 1];
// -1 is to eliminate terminating '\n'
writefln("got '%s' from '%s:%d'", s, client.addr, client.port);
```
```d
char[] s = cast(char[])ioCtx.buf[0 .. $];// please remember that
in `[0 .. $]` last index is automatically `length - 1` but just
buf[$] will be an error since there the actual `length` will be
used
```
I _think_ the above code is correct, please verify
