I'm reading a DataInput.
I have a variable number of bytes stored at the end of an input stream (may be in a file, may come from a socket, etc.).
I need EOF to tell me when I reach the end AND I need the count of the actual number of bytes of data.

This gets the data:

Code:
byte[] data = new byte[WAY_TOO_MANY_BYTES];
try {
    in.readFully(data);
} catch (EOF e) {
    // ignore
}
But I don't know how many bytes actually read. Can anyone think of a way to get the count, short of reading one byte at a time and counting them?
